Integrate Divi Theme + Pop up + contact form 7

Hi have a question i would like to integrate a contact form 7 shortcode in to the wpmudev popup plugin, right now i am using the Elegant theme Divi theme, but i cannot figure out how to make them work all together.

I have inserted the shortcode into the popup text area and i set it to display in 1 minute! That works fine the popup appears with the form inside. But now i would like to place a button on my page so when client click on this button the popup will show the form! i can’t figure out how to get this done i am pretty new in this.

By the way i have already set the “PopUp Loading Method” to Page Footer.

Hope you guys can give me a hand on this
