Pop-Ups trigger on query string.

For the Elementor Pop-Up, is it possible to trigger the pop-up? For example via a query string like: /?coupon-code

I've tried using the Advanced Rules -> When arriving from specific URL (Regex): (.*)?convention-coupon
But that doesn't seem to work, anyone has any clue to how I would state that if they are on a page where there is a part of the URL query matching that the pop-up would trigger?

Thanks in advance for further information.
