[keycloak-user] Keycloak ACL data access

Hello, Is there a way to manage fine grained authorizations with Keycloak like in the following scenario? There are Users and Reports. If i'm logged in as "user1", I can only view my reports So there is REST endpoint on Resource Server: GET /reports/ - Return set of reports that belong to logged user How can i use Keycloak to filter data records by user? Thank you for your help
