Allow user to change app notification sound

I have an app that uses Firebase Messaging to send notifications, and I have a set of sounds added to my xcode project resources, to play on the device.

I send the notification to users subscribed to specific topics, from my server like this:

"apns": {
    "headers": {
        "apns-priority": "10",
    },
    "payload": {
        "aps": {
            "alert": {
                "title": titleMessage,
                "body": bodyMessage,
            },
            "sound": 'alert.wav',
        },
    },
}

Now the sound "alert.wav" plays fine on the device, when the notification is received.

What I want to do is inside my app: I want to allow users to change the notification sound, from different sets of sounds.

Example: Option to play sound from: set 1, or set 2. and I would have them in my app as seperate folders with the same file names.

Is this possible in iOS? and how can I achieve it in react native?
