Tips for fixing torn screen on wooden exterior door

Hi Neighbors, I am looking for advice on how to approach fixing/replacing a screen on an exterior screen/storm door made of wood. These doors are pretty old and unique, and do not appear to have screen frames that could be removed and repaired. It looks like the screens must be attached under some wood trim. Not sure how to approach the repair or what type of service person to seek out. If anyone has a recommendation, I'd be happy to take it. Thank you, Laura Gordon Grafton St
