 ### `permission-<permission name>`
 
 **Optional:** The permissions to grant to the token. By default, the token inherits all of the installation's permissions. We recommend to explicitly list the permissions that are required for a use case. This follows GitHub's own recommendation to [control permissions of `GITHUB_TOKEN` in workflows](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/controlling-permissions-for-github_token). The documentation also lists all available permissions, just prefix the permission key with `permission-` (e.g., `pull-requests` → `permission-pull-requests`).
