Apple Pencil and Adobe Fresco.

on iPads, as we all know, there is a function to  "draw only Apple pencil".  This function, as I understand it, is supported by some applications and you can check it exactly in the "notes" application on the iPad. So on iPad it works.
The question is: should it work in Adobe Fresco or not? because I turn it on but  I can still draw with my finger and with a pencil at the same time. What is stopping me.
