How do I add a Google tag to a WIX page so that I can see when people click on a button on the page?

I'm new to Google Tag Manager. I've added it to my WIX site along with Google Analytics. I've added the proper IDs. I've created a Google Event Tag. I've created a trigger for the specific page. Unfortunately I cannot find specific instructions for adding the tag to the specific page. Any instructions on  how to get the tag on the specific page would be greatly appreciated.

Thanks
