show certain app controls all the time

Hello,

When Skype is open, I always want to show the default app-specific controls on the Touch Bar. The use case is that I, much like other humans, multi-task and tune out meetings and want to (especially) quickly mute/unmute using the Touch Bar when I'm in a call, but have 100 other windows open and can't quickly get to Skype.

So, how do I show the Skype controls all the time on the touch bar, when Skype is running?
