Click outside the button

Hello, guys!

I would like to know is there any way to detect click outside an object in Animate CC?

There is no problem to use it inside HTML DOM, I understand how to do that with parent node, but in CANVAS - no ideas (except lower layer with 1% transparency).

So, any ideas how to use JS for solving the problem:

1. Window is open.

2. Outside click closes the Window.

Thank you!
