Hello, I am having some doubts - namely I have a Play framework project, Controllers represent my backend, views my frontend. Now I want to enable only some users (with specific role) to access one of my views (html page). For now, whole communication works like this: JS sends request to Keycloak to login, if login is successful -> go to page, if not ->return error. 1. Do you think it would be better to somehow secure this frontend using my backend (written in Java) and how would I do it, since I really don't understand Java adapters....? 2. If it is OK to leave communication as it is, how would I forbid certain users to access some pages, since I can't find how to set necessary restrictions through code and on server. Thank you very much.
