Oauth2 configuration for prometheus

Did someone configure and used Oauth2 on prometheus config in order to integrate SSO with keycloak?

prometheus.yml

 oauth2:
     client_id: "dsdsf-sdfssd-vfdsd-23sdfs"
     client_secret: "sl;k96,;di0l;skdf;'lsgjs;';fks"
    scopes : "https://keycloak/oauth2/authorize"
    auth_url : "https://keycloak/oauth2/authorize"
    token_url : "https://keycloak/oauth2/token"
    api_url : "https://keycloak/oauth2/userinfo"

I tried to add these lines on my prometheus.yml but the when I restarted the prometheus service, I have INVALIDARGUMENT on the config.

Regards,
