Sonar Pen and pen connecting

Hi everyone, I recently discovered Nomad Sculpt and I saw that support for sonar pen was added in the 1.85 update but I can’t understand if there is something to set to enable it

I completely removed it because it caused some crashes on some Android devices so I don’t want to take any risks.

Oh, I don’t think I could fully use the app without pen pressure.
I will try to ask for a refund.
Thanks for the reply
