+```
+USAGE
+  $ csdx cm:stacks:bulk-assets [-a <value>] [-k <value>] [--operation publish|unpublish] [--environments <value>...]
+    [--locales <value>...] [--source-env <value>] [--source-alias <value>] [--publish-mode bulk|single] [--branch
+    <value>] [-c <value>] [-y] [--retry-failed <value>] [--revert <value>] [--bulk-operation-file <value>] [--folder-uid
+    <value>]
+
+FLAGS
+  -a, --alias=<value>                Uses the name of a saved Management Token to authenticate the command. The command
+                                     can only access the branches allowed for that token. This option can be used as an
+                                     alternative to` --stack-api-key.`
+  -c, --config=<value>               (optional) Specifies the path to a JSON configuration file that defines the options
+                                     for the command. Use this file instead of passing multiple CLI flags for a single
+                                     run.
+  -k, --stack-api-key=<value>        API key of the source stack. You must use either the --stack-api-key flag or the
+                                     --alias flag.
+  -y, --yes                          Skips interactive confirmation prompts and runs the command immediately using the
+                                     provided options. Useful for automation and scripts.
+      --branch=<value>               [default: main] The name of the branch where you want to perform the bulk publish
+                                     operation. If you don't mention the branch name, then by default the content from
+                                     main branch will be published.
+      --bulk-operation-file=<value>  [default: bulk-operation] (optional) Folder path to store operation logs. Creates
+                                     separate files for success and failed operations. Default: bulk-operation
+      --environments=<value>...      Specifies one or more environments where the entries or assets should be published.
+                                     Separate multiple environments with spaces.
+      --folder-uid=<value>           (optional) The UID of the Assets' folder from which the assets need to be
+                                     published. The default value is cs_root.
+      --locales=<value>...           Specifies one or more locale codes for which the entries or assets should be
+                                     published. Separate multiple locales with spaces.
+      --operation=<option>           Specifies whether to `publish` or `unpublish` content.
+                                     <options: publish|unpublish>
+      --publish-mode=<option>        [default: bulk] Publish mode: bulk (uses Bulk Publish API) or single (individual
+                                     API calls)
+                                     <options: bulk|single>
+      --retry-failed=<value>         (optional) Use this option to retry publishing the failed entries/assets from the
+                                     logfile. Specify the name of the logfile that lists failed publish calls. If this
+                                     option is used, it will override all other flags.
+      --revert=<value>               (optional) Revert publish operations from a log folder. Specify the folder path
+                                     containing success logs. Works similar to retry-failed.
+      --source-alias=<value>         Alias name for source environment delivery token (required for cross-publish). Add
+                                     delivery token using: csdx auth:tokens:add
+      --source-env=<value>           Source environment for cross-publish

+  -k, --stack-api-key=<value>        API key of the source stack. You must use either the --stack-api-key flag or the

+      --api-version=<value>          [default: 3.2] Specifies the Content Management API version used for publishing.
+                                     Use version `3.2` when publishing entries with nested references, otherwise, use

+      --branch=<value>               [default: main] The name of the branch where you want to perform the bulk publish
+                                     operation. If you don't mention the branch name, then by default the content from

+      --bulk-operation-file=<value>  [default: bulk-operation] (optional) Folder path to store operation logs. Creates
+                                     separate files for success and failed operations. Default: bulk-operation
+      --content-types=<value>...     Content type UIDs to perform operation on. If not provided, operates on all content

+      --include-variants             Includes entry variants (alternate versions of a base entry) in the bulk operation.
+                                     By default, only base entries are processed.
+      --locales=<value>...           Specifies one or more locale codes for which the entries or assets should be
+                                     published. Separate multiple locales with spaces.
+      --operation=<option>           Specifies whether to `publish` or `unpublish` content.
+                                     <options: publish|unpublish>
+      --publish-mode=<option>        [default: bulk] Publish mode: bulk (uses Bulk Publish API) or single (individual
+                                     API calls)
+                                     <options: bulk|single>
+      --retry-failed=<value>         (optional) Use this option to retry publishing the failed entries/assets from the
+                                     logfile. Specify the name of the logfile that lists failed publish calls. If this
+                                     option is used, it will override all other flags.
+      --revert=<value>               (optional) Revert publish operations from a log folder. Specify the folder path
+                                     containing success logs. Works similar to retry-failed.
+      --source-alias=<value>         Alias name for source environment delivery token (required for cross-publish). Add
+                                     delivery token using: csdx auth:tokens:add
