When you build a notification you can request access to show badge on app launcher.

You can try something like this

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        getSystemService(NotificationManager::class.java)?.createNotificationChannel(
            NotificationChannel(
                CHANNEL_STRING_ID,
                resources.getString(R.string.app_name),
                NotificationManager.IMPORTANCE_HIGH
            ).apply {
                enableVibration(true)
                setShowBadge(true)
            })
    }
