They remove identically to the scissor key caps on other MacBooks (16” 2019 Pro, 13” 2020 Air/Pro (Intel) and the M1 Air/Pro). They are quite tricky, but here’s the general idea. There is a hinge along the top edge of the keycap that snaps into the underlying scissor mechanism(for most keys). Your best bet is to try and pop the bottom two corners out of the scissor. I usually go in from the side and work my way towards the bottom with something really thin and flexible. Once the bottom two clips are unsnapped you should be able to tilt the keycap up a bit and pull it free from the hinge, just be careful because they are easy to damage.
