Log user in without creating a Database entry on Bubble

Hello fellow Bubblers!

I’m working on user auth with the API Connector and Firebase. My database is on GCP so I’m trying to use the Bubble database as little as possible (ideally, not at all).

Now my question is: how does this work with Bubble’s “Log the user in” action and the “Current user is logged in” check? I would really like to be able to use these convenient checks and actions but also get away with not creating the users in the Bubble database. Is this possible?
