How to implement Android push notification sounds

Hello! I implemented the push function. But when you push Android, you will not hear any sound or vibration.

Https://www.fusetools.com/community/forums/howto_discussions/sound_push_notification_on_android?page=1&highlight=bfff7a7e-a639-46e4-889d-1894af4b5f50#post-bfff7a7e-a639-46e4-889d-1894af4b5f50

I do not know if the feature is yet available in this forum, but I want to know if the alert is still available.
I followed the methods of this site.

Push.onReceivedMessage = function(payload, fromNotificationBar) {
    console.log ("Recieved Push Notification: " + payload);
    console.log ("fromNotificationBar="+fromNotificationBar);
    message.value = payload;
};

Looking at the implementation, around here.

I believe that if you add "sound":"default" to the JSON payload, you should be getting the default OS sound.
