Hello everyone! I had a question regarding using Supabase auth with Medplum. Supabase does not seem to be a true IDP such as Auth0, but can trigger an oauth flow to Google. Curious if I can still use it in the [following manner](https://www.medplum.com/docs/auth/methods/external-identity-providers) to sign a user into medplum but keeping users in the supabase system. I have pulled the Medplum repo down locally and modifying the packages/app/src/SignInPage.tsx to see if it is possible, but running into the following issue: "Unsupported provider: Provider could not be found".
