[keycloak-user] Proxying SAML Login

Hi, I have looked around but couldn't find what I was looking for. What I want to do is when user wants to login with IDP I still want the user to login via Keycloak UI and I want Keycloak to proxy the IDP. What makes sense to me is to have something like a new client which will use OpenID and then this client would proxy it to the IDP itself. Is this possible? If so then how can I do it?
