Automatically assign records to the queue
The custom object's record should be set as "Public Read Only" for visibility to all users but editable only by the owner. In case of picklist field edits, the record will auto-assign to the editing user's groups through Process Builder, allowing them edit access while restricting the previous assignee. A profile giving 'Read' and 'Edit' permissions and user-assigned queues are also needed in this setup.
