Activate the “YouTube Data API v3” in your project and add the scopes openid, email, and https://www.googleapis.com/auth/youtube.readonly for its consent screen. See more details in Setting up OAuth 2.0.

Access Scopes

The scopes are used by Google to limit your application access to the user account data. Read more about YouTube Data API scopes.
