In Contentstack, you can update the management token details after it is generated. However, you cannot modify the token value itself.
To edit an existing management token, log in to your Contentstack account, go to your stack, and perform the following steps:
Update the necessary fields such as name, description, selected branches or aliases (scope), stack-level permissions (read/write), expiration date, or manage rate limits.
Note: Manage Rate Limits is a plan-based feature. For more details, contact our support team.

Note: You can update most details of a management token, but you can't view or change the token string after you create it. If you need a new token value, you must generate a new management token.
