[keycloak-dev] How to refresh and update token

Is there a way to refresh token with Javascript Angular adaptor so that Custom User Federator is updated again? I'm actually storing token retrieved from another service provider as user attribute. It is stored first time when the user logs in (and saves the user data into the Keycloak database) but there isn't easy way to update the attribute with the adaptor? Thanks, -- Kind Regards, Jae Choi
