Connecting Supabase to Appgyver

I have been trying to connect Supabase to Appgyer for some time now and can’t figure it out. Can someone make a set-by-set breakdown of how to set up a collection and a single record? this will be very much appreciated.

supabase database has REST api by default , you should check their docs,
this are REST API sample from my database “perijinan” table

The issue for me is that I come from a design background and am a newbie so reading the documentation and trying it still does not work. I was hoping to get a walk-through.
