Which pen protocol version chuwi freebook support?

I want to buy a pen for my chuwi freebook. I found that it supports Microsoft Pen Protocol. But I can’t find information about version of supported microsoft pen protocol.
Do it supports tilt and version 2.0 of protocol?
If no, maybe pens with with support for 2.0, also supports older versions?
Does chuwi hipen h7 supported?
