how do I set my canvaspanel in my widget to hit test invisible in UE 4.23.1?

HOW IN THIS TUTORIAL ON THE 22:25 second it shows u but how?
Bing video q=how+to+make+a+hud+in+ue+4&&view=detail&mid=BE59C8F8A594FA0BCCA4BE59C8F8A594FA0BCCA4&&FORM=VDRVRV

the link doesnt work, but my best guess would be to search for the collision settings on either the canvas panel details or the widget component
