The natural way to use Firebase on mobile is using Android or iOS.
However, I'm in this situation where a client who developed a web app wants to receive push notifications when:
- The web app runs on a mobile browser
- The mobile browser app is in background
Is that possible?
Note: According to Firebase Documentation, client web apps can receive push notifications when they are in background, but I'm not sure if that extends to web apps running on a mobile browser in background.
