Customize Sidecar Touch Bar

Hi there!

I currently have a M1 MacBook Air and an iPad Pro 10.5 (2017) and use them together with sidecar.

I noticed there is a touch bar just like the MacBook Pro's on the iPad when using sidecar, but I can't customize it, it can only ever show the default icons for the open application. Not even the control strip shows.

I was wondering if I could customize the control strip even though I'm on a MacBook Air (that clearly has no touch bar on it's own). When I go to the settings part that controls the touch bar, I can try to drag the touch bar icons to the iPad, but it won't go into where the touch bar is, and if I try to drag it down to where the Pro's touch bar would be, nothing happens and my mouse pointer gets dragged into it until I close the configuration.
