FCM Notification in iOS doesn't play sound when received

Question

I am using Firebase push notifications in my iOS Application. Although I am able to send the notification by sending below payload, it doesn\'t play a sound when received. <

When using the FCM admin SDK, you have to specify sounds separately for Android and Apple devices:

let message = {
    notification: {
        'body': 'This is the message the user sees',
    },
    data: {
        'param1': 'specify some extra data here',
    },
    // Apple specific settings
    apns: {
        headers: {
            'apns-priority': '10',
        },
        payload: {
            aps: {
                sound: 'default',
            }
        },
    },
    android: {
      priority: 'high',
      notification: {
          sound: 'default',
      }
    },
    token: 'target FCM token goes here',
};

(Note: I've only tested the Apple settings thus far)
