[keycloak-dev] Queries on Custom Authorization

Hi Team, Kindly explain the below query: I want to have custom authorization, i.e a user can view certain pages but not some other pages. Certain components on a screen should be invisible and navigation to certain screens to be restricted. Does key cloak provide any such custom authorization api. I went through the document but could not find any explanation on this topic. Any help will be highly appreciated. Regards, Satya.
