How to implement real-time user presence with Firebase's .info/connected?

Hi everybody, I just want to know if the Firebase client package includes the built-in online/offline feature. Specifically, can we use it with an ESP32 and this package to:

1. Monitor the device's online/offline status (e.g., 'Device is online' → 'Device goes offline').

2. Maintain connectivity to a specified path ( .info/connected ) when transitioning between online and offline states, utilizing the feature Firebase provides.

Such topic should be asking in the community forum.

The Firebase Realtime Database and Firestore Database REST APIs do not support this.

You can set the device timestamp in the database periodically and use some backend cloud functions for polling check the timeout of device timestamp.
