plugin not working with “media”

I love this plugin; I installed on my website but it seems that it only works with pages and posts.

In this page: https://www.actbeyondocd.com/worksheets-workbooks-2/
there are 3 different documents -documents from the library- and we can only “applaud” one of them and then the other three get activated applaud too.

I would like to create something like this:
