Discourse ID fails to activate on my instance

I see this message when I try to activate Discourse_id on my test system (3.6.0.beta2-latest): enable_discourse_id: You must configure Discourse ID credentials ('discourse_id_client_id' and 'discourse_id_client_secret') before enabling this setting. I use a local Oauth server for OIDC here (keycloak). Maybe the two methods are interfering with each other??
