[keycloak-dev] How to customize Realm Admin Menu

Hi, I'd like to customize the realm admin menu. I've been able to use roles to limit the links shown to be: Realm Settings Roles User Federation Authentication I'd like to be able to hide 'Realm Settings, Roles and Authentication' (just showing the User Federation). Is it possible to define new roles that can be used to restrict the links, or could this be done via a theme?
