Override all BTT touchbar buttons and customize my own buttons for specific app


I have an app that I want to completely redesign the buttons and layout of the touchbar with. I've set up a conditional activation group and it appears to be working. When I add touchbar buttons, it is adding them along with all of the defaults.

For this specific application, I want to start with a blank slate and not have the defaults apply. How do I go about doing this? I've spent an hour messing around with various settings and have not had any luck.
