Push Notifications details:

With new push notifications lib we bring some changes to the setup process

• read the guide how to connect it and use https://wix.github.io/react-native-notifications/docs/getting-started
• in order to test Chat sample on Android, you need to create google-services.json file and copy it into project's android/app folder. Also, you need to update the applicationId in android/app/build.gradle to the one which is specified in google-services.json, so they must match.
• There was an issue on Android with receiving a callback when a push arrived and an app is in killed/dead state. We addressed it here: -- we created a patch to push notification lib - patches/react-native-notifications+4.3.1.patch - which is applied automatically when you do yarn (it's specified as a part of package.json postinstall step - "postinstall": "patch-package && npx jetify && cd ios && pod install") -- you also need to add <service android:name="com.wix.reactnativenotifications.JSNotifyWhenKilledTask" /> into AndroidManifest.xml file -- and now you can process the notifications in killed/dead state via the following code snippet:

    const { AppRegistry } = require("react-native");

    // https://reactnative.dev/docs/headless-js-android
    //
    AppRegistry.registerHeadlessTask(
      "JSNotifyWhenKilledTask",
      () => {
        return async (notificationBundle) => {
          console.log('[JSNotifyWhenKilledTask] notificationBundle', notificationBundle);

          PushNotificationService.displayNotification(notificationBundle);
        }
      },
    );
