This module expects that you already have the authorization in place and have accessToken stored at somewhere. You need to have below scope while getting the authorization from user.

1. gmail.modify
2. gmail.readonly Make sure that you do not have gmail.metadata scope. Looks there is some bug in Gmail API.
