My target is to get the information in my app of the origin of the user: does he/she come from a Google Ad click?

The flow is: Google Ad -> AppStore/GooglePlay -> App Download -> App Opening -> Firebase custom event (like Register or whatever).

When we connect Firebase and Google Ad together, we can have the conversion funnel available in Google Ads.

It means that the tracker is available in Firebase within the iOS/Android app.

Is it possible to retrieve this tracker from Firebase? I want to send this information to Mixpanel that the user downloaded an app thanks to a Google Ad click.

PS: any answer is good, but I will use React Native or Flutter to implement this behavior.

Thanks!
