Scopes [hcp.manageAuthorizationSettings] exceed the scope granted by the resource owner

Hi,

I'm going to manager roles and users using Authorization Management API. I follow the instruction at Using the Authorization Management REST API but I'm having the following error when I try to get access token:

   {"error": "invalid_scope",

     "error_description": "Scopes [hcp.readAuthorizationSettings, hcp.manageAuthorizationSettings] exceed the scope granted by the resource                                             owner"

   }

I spent half a day on this but still no luck. Please help if anyone knows what causes the issue.

Many thanks,

Liang
