Really useful package 🙌

1. Summary

4. Problem Description & Proposed Solution

I am using the notifee displayNotification method to display a foregroundService notification on android like this:

notifee.displayNotification({
    id: 'timer_foregroung_service_notification',
    title,
    subtitle,
    body,
    android: {
      channelId: TIMER_CHANNEL_ID,
      asForegroundService: true,
      color: color as AndroidColor,
      colorized: true,
      smallIcon: 'ic_notification_pic',
      pressAction: {
        id: 'default',
        launchActivity: 'default',
      },
      onlyAlertOnce: true,
    }
  });

I noticed that when I call this method for the first time after the app has been inactive is takes about 10 seconds before the first foreground service notification shows up. But once the foreground service notification is active the subsequent notifications pull through straight away. If I exit the screen, and come immediately back in the foreground service notifications work correctly straight away. It seems there is a delay when starting after a long time inactive (above 2 mins).

After some searching, there are a few people online with similar issues, and the delay is potentially cause by android itself:

mauron85/react-native-background-geolocation#560

It seems to get the foreground service to start immediately we need to pass FOREGROUND_SERVICE_IMMEDIATE into setForegroundServiceBehavior().

// Native Android code
builder.setForegroundServiceBehavior(NotificationCompat.FOREGROUND_SERVICE_IMMEDIATE);

I wanted to patch the package but I couldn't find anywhere in the codebase to attach this setForegroundServiceBehavior. Could the package expose this as an option, or could you point me in direction of how I can patch the package to show this option?
