We are migrating from Parse to FCM (Firebase Cloud Messaging).
Parse has a great endpoint we've used to get the number of devices subscribed to specific topic (Parse calls is channel): https://parseplatform.github.io/docs/rest/guide/#querying-installations
I cannot find it's equivalent in FCM. I know there is Firebase Analytics dashboard, but I'm looking for API endpoint.
Does FCM provide any API endpoints which could be used for analytics purposes?
