Push Notification payload not contain sound Key

When the app is in the background and other user send a message then there are no sound is play on notification only banner is shown
When i was inspect the apns Payload then found that there are no sound key on APNS payload

[AnyHashable("room_id"): !rhgiznzzehBqpLPiKl:dev.ravenglobal.app, AnyHashable("aps"): {
    alert =     {
        "loc-args" =         (
            nick,
            Zxcxzc
        );
        "loc-key" = "MSG_FROM_USER_WITH_CONTENT";
    };
    badge = 3;
    "content-available" = 1;
}]

There are any way to add sound key in apns payload.

Start by tracing where the APNS payload shown in the issue is assembled. Done means the payload includes a sound key for background message notifications and the notification plays a sound instead of showing only a banner.
