I recently utilised a web-site that required the use of Google's "Issued AuthSub Tokens".
Once finished, I was offered the option to remove the approval I'd given for this activity. The removal option took me to a Google sign-in page, after which I got a screen named "Authorized Access to your Google Account", showed various "Connected Sites, Apps, and Services" , and listed the services concerned together with a Revoke Access button.
No problems with this, but how would a user reach the same screen from their browser if they didn't know the URL I happened to copy when departing the specific web-site I'd been using originally?
I cannot find similar screen or settings when logging on to Google in the normal manner, e.g. when collecting email.
