I'm thinking about implementing Firebase Cloud Messaging without implementing a firebase database and it's unclear to me which features of FCM are supported without having a firebase database.
For instance, getting message delivery statistics (https://firebase.google.com/docs/cloud-messaging/understand-delivery) and sending notifications via the firebase console (https://firebase.google.com/docs/cloud-messaging/js/send-with-console). It doesn't explicitly say whether you need a firebase database in either of documents but I'd like to clear about that before implementing it.
So my question is, do you need a firebase database to send notifications via the firebase console or to view message delivery statistics? I know for the latter you need to implement google analytics. And also as a bonus, are there any firebase features that depend on having a firebase database?
Thank you
