When I configure a Google Workspace Enterprise Connection, it contains this tab. There is nothing referring to it in the documentation Connect Your App to Google Workspace and without a Google Workspace account of my own to test it, I’m unsure what it’s purpose is.
If a Google Workspace admin is deleted, any Google Workspace Enterprise connections they have set up and authorized will need to be reauthorized by a new Google Workspace admin to avoid login failures. This can be done by having the new admin use the link in the Setup tab for the Google Workspace Enterprise connection.
I’m sorry for the late reply, but I hope this enlightens the situation.
Thanks,
Remus
