PWA Dynamic Plugin

Friends, hello everyone! Has anyone encountered the WP Dynamic plugin? Specifically interested in the problem with installing the application by clicking on the button. I can’t do Show Install : yes (as in the demo version here /), accordingly, the entire further chain of actions does not work. I did everything according to the instructions. Please help!

How about a link to the plug-in?

I use this OneSignal MAX Push Notifications Plugin | Bubble and this PWA Dynamic Plugin | Bubble
