The pressure of the (ACPI0C50:00 2D1F:0163 Pen) is always 0.00

Input 1:

sudo libinput debug-events

Output 1:

 event8   TABLET_TOOL_AXIS +371.972s            175.65*/71.95*  tilt: 0.00/0.00 pressure: 0.00

Input 2:

xinput --list-props 14

Output 2:

        libinput Tablet Tool Area Ratio (580):  0, 0

* note: I intentionally modified (libinput Tablet Tool Pressurecurve) to always be (1) so why does it produce 0.00?
