No, I am afraid I cannot help regarding this

If you want to give it a go, check out the docs https://next-auth.js.org/configuration/providers/oauth and the existing provider https://github.com/nextauthjs/next-auth/tree/main/packages/next-auth/src/providers

Took a first stab at it. The doc is really helping to bootstrap the provider, well done. I'm stuck now, will need some help to debug it further.
