Get current lat-long coordinates in Embed widget code

[JohnSasso2]

I included the Embed widget in my web app, and connected it to a polygon feature layer.  In code (say, Javascript) in the Embed widget, I want to access to lat-long coordinates of where ever I click on in the map within the polygon.  How can I accomplish this?

I have the same need, has anybody figured out a way to accomplish this?
