Adding an XY to a List using Arcade

[APBlough]

I am trying to add an XY coordinate of the center of a polygon to the list. 

Currently I have a WebMap that is filtered using the dashboard and another tab of the WebApp so that they can find the project they need and then open the other tab and edit the attribute. 

As a way to help locate the project between he two map tabs, I want to add an XY to the list so it is easy to find the projects between the two maps.

I have another ID they should use to search but I wanted to figure out the arcade for the XY.

Any help would be amazing!

I'm not having any luck on how to load things like this into our dashboards. Did you have any better luck? Or any suggestions on where to search for information?
