How to input third party code into my website

Hi! I have contacted the wix service through the ‘call back’ option and I was able to locate how to get to the code panel. I am trying to use a third party website, Reftagger, which allow me to mouse- over bible verses where it will pop up. I am not sure what code to input from this website as it seems very confusing to me. I have already tried certain things and I don’t believe I am doing it correctly. If there is any way someone would be able to look at Reftagger and determine what code I need inputted into the “code panel” on my editor site that would be great. I am lost!
Thank you so much.

I looked at an HTML article in how to input a website and so fourth. I am wondering… If I am just looking to be able to acheive the ability to mouse over verses and the verse pop up… do I need to embed the site? Or would I just need a embed a simple code and not the site? The sight is called Reftagger. Thank you!
