Moengage is one of the worst analytics software I have ever worked with...
Integrating it into a react website is a pain in the ass, they don't have a npm package, you need to add a script tag to html file.
It also has a wierd bug that the service worker they mentioned in the documentation doesn't work when the debug logs are off.
Aaaargh. Now I have to make a service worker handler to import this service worker and see if it works...
