    We can assign client roles to realm roles (composite:true)
    realmroles->for-specific-role->menu-action->Add associated roles
        now it is composite role
            # jwt.io: .resource_access.myclient11.roles=client11_admin,client11_user
            # https://github.com/ali-bouali/keycloak-integration-with-spring-boot-3/blob/main/src/main/java/com/alibou/keycloak/JwtAuthConverter.java
            # JwtGrantedAuthoritiesConverter -> SCOPE_, split(by space) "scope" attr of jwt

        user can also be a composite
    /realms/<relm-name>/well-known/openid-configuration
        token_endpoint
        grant_type: password
        client_id: ...
        username: ...
        password: ...
        -> refresh_token is also provided
        token can be pasted to jwt.io
        @PreAuthorize("hasRole('client_role')")
            defaultRolePrefix="ROLE_" // !!!
