Need help configure a project to download Google Class Room

[ahammadah]

I tried to download material from my son's google class room, I stored his credentials in the project, however I always ended up in the case where software kept digging in the login domain (account.google.com - even when I tried excluding it explicitly) rather than reaching what matters to me which is the domain classroom.google.com.
can someone help me fine tune this project to work the way I want?
