See this. It’s the first result on Google for “wn722n v4 Linux”
As I mentioned, you’re not in need of Qubes support - just plain old Linux support - as long as you know how to attach the device to your AppVM
The reason lsusb/lspci were suggested as a step, by the way, is because the information there will help you determine the underlying chipset used by the device. The driver you need will need to be designed for supporting that chipset
Hope this is helpful
