Hi, I'm trying to find the best approach to passing thru custom url parameters from our application to keycloak and for use in the keycloak freemarker templates (login/otp etc) http://localhost:8080/auth/realms/lobby/protocol/openid-connect/auth?clie... This then successfully loads the login page within Keycloak BUT the "session_state" and "custom_param" params are lost and not available for use in the freemarker templates.. Whats the best approach to expose these custom params to login.ftl/loginOTP.ftl etc ?
