Supabase? Need to create new app?

I have a full app in adalo with adalo database / collections.

I want to use supabase instead. I watched the 3 videos, but that person is starting an app from scratch.

I do not want to use XANO, but its the only option I see. I paid for Pro specifically to use Supabase. There was no mention anywhere that I have to pay for team to use Supabase.
