[keycloak-user] Adding custom HTTP request attribute after successfull keycloak login in custom Authenticator or User Storage Provider?

Hi all, I developed a custom User Storage Provider which allows to federate users from a external database. I would like to know if it is possible to add a custom attribute to the HTTP request after successfull login, just in a similar way that KeycloakSecurityContext instance is set in attribute "KeycloakSecurityContext.class.getName()" (for example in keycloak class ServletRequestAuthenticator.java). It would be really good to do that in User Storage Provider or a custom authenticator. Context: I need to set up roles to the authenticated user after successfull login, but before entering to the application. Keycloak roles that not fit my needs. So it would be good to add this bunch of roles in a custom HTTP attribute. I appreciate if somebody faced this and have a cute solution to this :slightly_smiling_face: Thanks in advance,
