Hello! I'm currently using Firebase for my app and I'm looking into moving out of it for a couple of reasons. At the moment, I mostly want to migrate out of Firestore and to postgres. I'm looking into Supabase because I'm interested in the real time updates of the db. I have a few questions about that: - Realtime stuff: The doc (https://supabase.com/docs/guides/database#realtime) explains the server side aspect of it, but I couldn't find a code example on how it works client-side, is there a sample somewhere? - RLS: all the RLS samples in the doc assume that the authentication system used is the Supabase one, but for now I want to keep Firebase Auth as the login provider. Is that possible? Thank you 🙂
