By default the this code in the Form only shows the people I often work with.

Choices([@'List'].'PeoplePicker')

I want to show only users filtered by Office Location dropdown.
If been trying for days creating collections and variables, using our AI or online AI's. None of there solutions are working.
In some case I could make it work but the it was a struggle to Patch it together with the Submit. The display in the Form was not refreshed. I gave up. Why do they make it so complex!!!
