My headliner was pulled down when I had a windshield installed. Can it be fixed on 2004 Buick Rendezvous

It is pulled down about an inch in the center of the windshield, by the rear view mirror. I don't know if there is a clip or how the headliner is attached. Can something like this be fixed or will this be a permanent issue.

Let upholstery shop take a look. What did the glass shop that did the work say about this?
