Apple Pencil Pro (also known as the 2nd generation Apple Pencil) is indeed not compatible with the 10th Generation iPad. The 10th Generation iPad only supports the 1st generation Apple Pencil. Unfortunately, the Apple Pencil Pro is designed for iPad Pro and iPad Air models with magnetic charging, and it won’t work with the 10th Generation iPad.
You might want to consider either getting a 1st generation Apple Pencil or upgrading to an iPad Pro or iPad Air that supports the Apple Pencil Pro. As for asking 紫檀 parents, that's a good idea—some might have found creative workarounds or have recommendations!
