Additional Context

For this feature to work you first need the environment variables GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET set up; for testing you could go to console.cloud.google.com and make OAuth consent screen of type desktop. The user is prompted to consent and authenticate using Google consent screen. If the files are made with 2fa, then further use requires google authentication.
