I have a custom created code for a pop up box written by a techy friend that I would like to appear on the shop page of my store. I am using a collection with "all products" as my main shop page. Can anyone show me the correct location in the liquid code to paste the code for the pop up? I am using the canopy theme if that helps. Here is my shop page: https://glory-garden.myshopify.com/collections/all Thank you!
