In the Quickstart code example we can see that for the admin endpoint, the user needs to have the "admin" role assigned in order to proceed. This is a great feature.

However, from what I noticed, this function checks only the roles that we can find under "realm_access" -> "roles".
There are also other roles that can be found under "resource_access" for each defined client in keycloak.

How can I create this filter based on roles with a custom keycloak client that has its own custom roles?

Thanks in advance for your reply!
