However, queues cannot be assigned as owners of records created by guest users because guest users do not have access to queues. Setting the default owner for records created by guests is an option in Experience Cloud sites that allows NMH to specify who will own the records created by guest users on their public site. Any active user in an org can be assigned as the default owner of records created by guest users, as long as they have the appropriate permissions and access to the object.
