What is the best way to do authentication, with correct re-rendering in NextJs with Supabase?

My mind says to have a context/state management system's provider around the app, and attach the supabase `.auth.user()` return to a state?

But is there any good documentation on doing it correctly / the best way?

This seems to be where many are ending up with Next.js/auth process.  I don't use NextJs though so just guessing what you are looking for.
