[Plugin: OptinPop] Popup on click instead of hover?

I’m using OptinPop plugin and it works well. I have it set to “on exit” so the popup window appears when leaving the site. My issue is that the popup happens when you hover the mouse outside the border of the website, which doesn’t necessarily means that the user is trying to leave the site.. I would like the popup only to happen when the user CLICKS away from the site (type new url or click “back” to an external link). Is this possible.

Any help is appreciated.
