Multiple index.html for one angular application - tracking codes issue

Question

I'm working on an Angular application which is split by libraries in NX.js into countries (each country is a separate library). Business wants each country to have its own tracking codes. The application knows for which country it works based on the url example.com/dk/ in this case angular lazy loads the dk library so I have no problem with that but I can't change index.html because the application is already up...
