I'm using Admin - Groups UpdateGroupAsAdmin API to update description of the workspace.
Workspace access is configured: service principle, which I use to authenticate API, is set as Admin for my workspace (also as described in this thread Unable to patch reportgroup name with a service principal account).
But when I run "Groups UpdateGroupAsAdmin" request either from my C# code or from Postman, I receive 401 Unauthorized error.
Are the needed some specific rights to be set for service principle to execute this PATCH query?
Thank you very much in advance.
