I recently switched to a new theme (Old theme was Make; new theme is BuddyBoss). The only thing I can't re-create is a button that when clicked displays a modal opt-in form. I had this working on the old theme, but can't figure out how to do it on the BuddyBoss theme. Adding a button to the Home page is simple enough with the WP block editor. But how do I link my form to the button?
