TouchBar area that pipes in whatever would be shown on the default Apple TouchBar

I know it's not possible to put Apple's default buttons on the touchbar as per this request - Using Default Apple Toucbar buttons within BTT Touchbar

Would it be possible to create variable space area on the touch bar that just displays 'whatever apple would be displaying at this time'?

For example, if you we're in Notes, this area would display the notes default button set.

no, I can either replace the Touch Bar completely or not at all. The system doesn’t allow anything else ;-(
