Allow search by attribute in admin console

As admin i can use the attribute search to find users.

I have added a new user to the master realm that is part of a group with these permissions for a specific realm: manage-users, impersonation, query-users, view-users, query-groups.

While the default search works, the new user has an empty dropdown list for the attribute selection when using the attribute search.
What permissions or settings am I missing to make them selectable?

I am running Keycloak 24.0.2
