You could try using conical rubber bumpers to create an angle, or I’ve seen adhesive laptop stands that folks have used for tenting keyboards that I wonder if they would work for wrist rests too.
The only problem I’ve had with them is that they leave a little grid mark on your hands after a while, but they’re solid for flat keyboards.
Here to also say that Lor is great. Definitely gonna check out Others by No One based on this.
You’ll be fine. Just be patient as your muscle memory adapts.
