Where is Google Analytics (G4A) being added?

[daveh0]

I just took over some dev responsibilities for an existing shop who has cut ties with the previous developers (and they have not 1 technical person in-house who knows anything about what I'm asking). I need to do some Google Analytics related tasks and for the life of me, I can't find how/where it's being embedded in the pages. I know that it IS being embedded because I can see data in the reports interface.

I don't see a Google and YouTube channel installed and their measurement ID is not entered into the Google Analytics section of Dashboard --> Sales Channels --> Online Store --> Preferences. I also searched source code for the measurement ID and came up with nothing. And finally, none of their installed apps seem like they would be where it's happening, but just in case, here's what they've got:

Any suggestions as to where else I might look for where GA is being added?

It was being added as a Shopify Web Pixel (using Analyzify) - https://analyzify.com/shopify-google-analytics
