Apple Pencil double tap not working with Sidecar on Mac mini

Hello,

I'm using sidecar between an ipad pro and a macmini. I'm also using an apple pencil.

I have enabled "double tap option on apple pencil" in my monitor settings of the Mac mini.

There is one issue with the pencil : Double tap does, in fact, not work.

Has somebody figured out a workaround ? Even if it's not apple-y ?
