Whiteboards could really do with palm rejection for use on tablets

Using Whiteboards on an iPad with an Apple pencil, feels nice and light weight, but I have to be really careful not to touch the screen with my palm else I end up with a long line connecting where my palm touched and the Apple pencil. I presume this is the same for other tablets and this form of device is where Whiteboards could be really useful.

For examples of apps that do it really well, Procreate has great palm rejection. Hopefully this is possible for Logseq. Thanks
