Google FCM push notification implementation

Implementation steps

1. Copy the data of firebaseConfig to your project.

   var appID = 0; // Your Application ID of ZEGO ZIM
   ZIM.create({ appID: appID });
   var zim = ZIM.getInstance();
   
   var config = {
       // From firebaseConfig
       apiKey: '',
       authDomain: '',
       projectId: '',
       storageBucket: '',
       messagingSenderId: '',
       appId: '',
       measurementId: '',
   
       // From Web Push certificates
       vapidKey: '',
   }
   ZPNs.getInstance().register(config, zim);

2. Download the latest version of ZPNs SDK and copy the firebase-messaging-sw.js file to the project root directory.

3. After the above configuration is completed, please contact ZEGOCLOUD Technical Support for offline push related configuration.
