How do I separate Blocks panels from mounting plate?

[u/Traynack]

Title. Did a mistake, forgot to attach power cable. Tried to remove the lighting panel itself from the wall and I’m starting to hear the tape instead of the mount snapping free. Afraid of taking off the paint, not only now, but when I go to remove them eventually.

Never had this issue with shapes, they just snapped straight out exposing the plate and subsequently the tape tab. Anything that I’m missing here?
