Embed Kartra exit pop up on SS pages

Site URL: http://travelmemoriesmadeeasy.com

Hello. Newbie here and clueless about code. I've created an Exit Pop Up in Karta and I have a URL as well as embed code. Where do I place the embed code (or URL) on my SquareSpace site so that it pops up when people exit?

Here is the URL: https://travelmemories.kartra.com/page/qlV4

And here is the code: <script type="text/javascript" src="https://travelmemories.kartra.com/page/embed/WALPiQyxaflF"></script>

Thanks!
