How to insert a “click popup form” in the beaver page?

[RETCH]

Hello all,
I built a DEALS page via Beaver builder. And I set two “CLAIM COUPON” buttons on the page.
Then I have modified an Email Collection Form with Popup Maker plug-in. After editing the pop-up, I got some CSS code, but I don’t know how to use it.
I hope that after visitors clicking the button, it will popup the Email Collection Form. My question is how can I do to integrate the pop-up with the “CLAIM COUPON” buttons?

Set the same class (CSS Selector) in the BB Button and the popup.

Thank you. Problem solved.
