Is it possible to get a click event from the chrome external protocol request?

问题

Is there any chance to track the click event on this div/pop up?Like if a user clicked on "Launch Application" button or "Do Nothing" button?

Also,is it possible to know whether the div has actually appeared in the first place? ( I know we can track through on blur event but it isn't accurate)
