Issue Summary:
I want to use Firebase Notifications to send messages on the App and the Web (mobile and www. website).
I know that Google Analytics for Firebase automatically logs such events like:
notification_foreground,
notification_receive,
notification_open,
notification_dismiss.
I also know I could use Firebase Analytics' events, parameters, and user properties to trigger and build tags configured in the GTM and send this information to GUA.
But I have two questions:
If I’ll add source, medium, campaign as custom data (key & value) while sending notifications, could I see them later as parameters for notification_open event?
User entered the website by clicking notification sent through FCM. What should I do to see source, medium, campaign for this visit at Universal Analytics (implemented on the website through GTM)?
