My panels on the CLIPPER have screws with the plastic caps, so are easy to remove.
Are you screws hidden in the fabric???? maybe access from below and also inside front cabinet??
When I enlarge your picture, I think I see two wood plugs along the top of the panel. Pull these out with a sharp pry, Knive etc, and the screws will be underneath???????
Sorry I can't be of more help on this project.
