Pop up form not triggered by tapping button

I have an issue when I set up the animation and trigger for my pop up form. When I tap the “Book free demo” button pop up form doesn’t show up. I am not sure why this is the case while I just follow this article step by step here. (How to build a pop-up modal in Webflow | Webflow Blog)

(The original design I have the modal hidden from the interaction design)

When I click “Book free demo” nothing happened. Seems like modal still pops out but the visibility is 0.

Thanks for the help
