Intercom mobile push - can customize push notification sound?

Hi, i wonder if Intercom Push support custom push noti sound feature in current payload ( For iOS ).

I couldn’t find in documentation, so I’m not sure it’s feasible or not.

Let me share with the current Intercom push payload. Thank you.

[AnyHashable("receiver"): intercom_sdk, AnyHashable("uri"): <null>, AnyHashable("intercom_push_type"): push_only, AnyHashable("aps"): {

    alert =     {

        body = "Have a nice day!";

        title = "Hello";

    };

    sound = default;

},
