Can community tier account use Contentful Management API?

I am in the community tier account with admin access and I want to bulk update an entry in multiple (200+) contents. I have the script ready and I kept getting 401 - status, Unauthorized - statusText with access token invalid.

Question is, do I need to use at least a basic account in order to use this Contentful Management API endpoint? Or I am able to as community tier but there is something wrong with my script or my personal access token?
