on the new Google identity API, I can not find documentation as to how to log-out a user besides using the revoke method
What is the method of just logging out a user, without breaking the connection to the application completely?
I am using JS in VUE.
The new Google Identity Services library (aka Sign in with Google library) does not support user session tracking unlike the deprecated Google Sign-in library.
Developers are responsible to track the user sessions of their sites. See Session state and Listeners section.
