Make use of .well-known OIDC /endsession endpoint

[Moshyfawn]

I read quite a few federal logout discussions & issues in this repo on the topic that basically come down to creating a custom Next.js API endpoint that calls a hardcoded /endsession URL to kill the server session when calling next-auth signOut method that only kills the client session.

What I'm trying to wrap my head around is, is there a recommended way to utilize the OIDC .well-known data to call the value of the end_session_endpoint field instead of writing a custom endpoint and constructing a URL to and the server session?

Can it be a signOut config?

P.S. I saw that federated logout is smth that the next-auth team were looking to adopt. Would love to know if it's still the case
