Add Spring Security OAuth2 Client endpoints

[Dyskal]

Hi,
Is there a way to add spring-security-oauth2-client endpoints, like the oauth2 callback uri /login/oauth2/code/{registrationId} & the one to generate the oauth2 login link /oauth2/authorization/{registrationId}? (Those can be customizable)
Or is it possible to add entries to the OpenAPI without a Controller?
Thanks

moreover, I had group-configs in my application.yml based on path matching, and if I add manual endpoints in my OpenAPI/OpenAPICustomizer bean, they are not accounted in groups.
