[keycloak-user] Keycloak adapter for single page app

Hello, I have a single page web app that mostly use ajax to retrieve data from REST services, it also have some polling requests going every few seconds to check for changes on server. My take is that i should use js adapter to protect my app, however, we want to store authorization artifacts (permission, resources, ...) on KC server and using JS adapter force us to use public client which disable authorization. Is there a way to use js adapter with authorization? I use KeycloakAdmin client to query the permission from KC server directly btw Thai Le
