# https://quarkus.io/guides/security-keycloak-authorization
# from that guide, we ultimately found that we hit GET /resource_set described at:
# https://github.com/keycloak/keycloak-documentation/blob/main/authorization_services/topics/service-protection-resources-api-papi.adoc
# when we get the resource, we just hit the token endpoint and provide the resource and scope, and token will say pass or fail.
