BTT - //Desktop - No Touch Bar buttons in full-screen mode

Dear team.

I'm just trying to make my BTT work for my //Desktop apps.
My touchbar customization is working for all my Mac apps, but nothing appears for my Windows 10 apps when I am in full-screen mode, it works well when I am in Coherence Mode.
I have created some basic command for a windows application, but when I am on the app, I have the message telling I did not configured anything. I've tried several windows app, same behavior.
I think I'm missing something but I cannot get the point.
Please do you have any ideas ?

MacOs 10.14.3
BTT 2.728
// Desktop 13.3.0
Windows 10 Pro

Thanks a lot !
