If this happens, we should refresh the locally stored auth token with a new one, versus the whole auth life cycle, which would be a different error generated if the auth code had expired.

[kitplummer]

The refresh_token is not coming back with the authorization_code flow in the graph-rs lib. Need to investigate more.
