One can define an OAUTH2 server easily based on the quarkus documentation.
quarkus.oauth2.client-id=XXXX
quarkus.oauth2.client-secret=YYYY
quarkus.oauth2.introspection-url=https://example.com/oauth2/...
How should I configure quarkus if I have to give the option to the users to choose their own OAUTH2 provider (github, gitlab, whatever)?
