v0 integration Supabase existing account vs vercel managed

Was building a few projects in v0 and started to build a supabase db integration and realized it created a new account that is managed by vercel rather than allowed me to just provide creds to my existing. Now I have two accounts, but my pro account is non vercel managed. Am I fighting an uphill battle and should just use vercel managed for the best practice integration or can I somewhere put my creds in and switch over?
