Is it possible to leverage Firebase Cloud Messaging (FCM) in AngularJS for real-time chat functionality? As far as I know, current capabilities do not support this. Please correct me if I'm mistaken.
At the moment, two-way messaging (receiving and sending messages) using FCM is feasible with Android SDK, iOS SDK, Chrome Apps and Chrome plugins. However, JavaScript frameworks (specifically those categorized as "Websites in Chrome") can only make use of one-way push notifications according to documentation found here:
Websites in Chrome can implement push messaging through service workers and web app manifests following the Webpush standard.
