Hi, there, and welcome!
Here's what our Customer Service team told me:
This cover has 4 clipping points, 2 at the top and to at the bottom. To remove the cover, you will need to force out—with a flat screw driver—the bottom 2 clips and then push it up. (see first attachment)
The customer also might need to try to push these 2 other clipping points from the back. (see second attachment)
Hopefully this helps.
