Brush Pressure Option Not Available

[Bacchinif06]

Hi everyone, I'm using an XP-Pen Deco 02 Graphic Tablet which is 100% compatible with Illustrator as clearly reported on the manufacturer's website. I've already downloaded the latest drivers and all of my programs (including Windows) are up do date.

Somehow, I'm not getting the option to enable brush sensitivity with my pen. How can I solve it?

I'm on Illustrator CC on a DELL XPS 15 4K 2019.
