When using OAuth2 credentials, the gateway should support refreshing tokens automatically when access tokens expire (one hour after the refresh started).
Microsoft OAuth2.0 is not supporting refresh token flow related in the "RFC RFC 6749 - The OAuth 2.0 Authorization Framework"
We already implement a workaround in AzureDataFactory and Databricks to renew the token every hour but it's missing in PowerBI's datasources.
It was easy to implement it and I hope it will be done for powerbi's datasource authentication workflow with SP.
