Google Analytics Integration with Forge App


I am trying to set up Google Analytics to track our Forge app usage although I’m quite confused about one aspect and I was wondering if someone could help…

When setting up the Stream, it asks for the URL of the “website”. Seeing as the forge app doesn’t have a public domain and URL, what should you put here? Does the Stream URL even matter seeing as the Tag will be the one collecting the data?

Any guidance on this will be greatly appreciated!

Many Thanks.,
