Microsoft Stream (Classic) and migration

Hello, 

I hope you're well. 

I am trying to run the stream migration tool Powershell to get the output of stream video reports.

however, I get the error code below. 

any tips or guidance will be helpful to me.

11/09/2023 11:27:52 {"error":{"code":"Forbidden","message":"The authenticated user is not authorized to access this resource."}}

11/09/2023 11:27:52 System.Net.WebException: The remote server returned an error: (403) Forbidden.
