In keycloak-server.json, if we add the following"authenticator": {"test-authenticator": {"config1": "xxxx"}}the value of config1 can be retrieved in the factory class init method as:config.get("config1")Now, in the same way, if I want to get configs in the init method of a RequiredAction class instead of an authenticator, how do I set it in keyclock-server.json? What will be the exact syntax? Is it possible?
