KongEE OpenID Connect Plugin - ACL plugin ignores groups returned in Access Token

Hi,
I’m using Kong EE 0.34-1.

I set up a service that’s protected by the OpenID Connect plugin and the ACL plugin with a whitelisted group, ‘admin’.
User authentication works as expected, with Kong picking up the correct group (‘admin’) from the Access Token for the authenticated user.
According to the OIDC plugin documentation the ACL plugin can apply ACLs based on the groups from the authenticated_groups_claim.
The Kong logs suggest that the ACL plugin ignores the groups because there’s no consumer involved (even though I specified an anonymous user):

I suspect we’re waiting for this to be merged into Kong EE:
feat(acl) add support for authenticated groups (for 3rd party authentication)
