Touch Bar appears blank when my app is run, even though I've added lots of elements to the Touch Bar in Storyboard.

I'm creating an app that uses the Touch Bar, I set up the UI, added a Touch Bar to the correct view controller and ran it, but the Touch Bar on my actual MBP was blank.

I don't have any Touch Bar simulators open, I've tried adding it to the Window Controller instead of the View Controller, but nothing.

Using: Xcode 12.5.1 MacBook Pro, M1 (Big Sur 11.5.1) Storyboards & Swift.

Any suggestions? Thanks! :)
