How to edit code on Edu-clean home page


I need to install some code on the edu clean homepage.

I have added some code (for a popover) into my header.

I now need to drop a short code into the page where I want to popover to appear.

Where can I do this for the homepage of the Edu-clean theme?

I've struggled with the WPMU popover for over a month now and have moved on.
