Modal Recaptcha Challenge windows goes behind the modal

Does anyone knows what’s the css selector for the re captcha challenge window? I did a modal that has a contact form with the recaptcha widget. The problem is that when the pop up window that lets you select the images to show that you’re a human comes up, it goes behind the modal.

I tried setting a Z-index to the widget, the whole form and try to find the style tag for that pop up but no luck, it goes behind everytime. I think that’s a Iframe, but I’m not sure.

You can see in the image that the popup is actually there but behind the transparent overlay div.
