Redirect parent after close of form submission lightbox

Hi,

I’m trying to send the user to my actual website automatically after receiving the success message from completing a form submission.

When the form is complete the lightbox pops up, but I can’t manage to redirect them after they close the lightbox.

I’ve tried this:

var closelightbox = document.getElementById('element-id');
closelightbox.onclick = redirectPage;

function redirectPage() {
	window.top.location.href = "https://www.example.com"; 
	return false;	
}

For element-id, I have used:

ubpoverlay-overlay
ubpoverlay-close

It works on elements within the lightbox but not anything outside of the lightbox. Essentially I want to click anywhere on the page and be redirected.

And just body wide:

$(document.body).click(function() {
window.top.location.href = "https://www.example.com"; 
});

Any ideas?

Thanks
