on device tip amount returns null on ios

[jp7]

Describe the bug
on device tip amount returns null on ios instead of returning the amount entered on the reader device

To Reproduce
Steps to reproduce the behavior:

1. Connect to a wisepad reader with a location with tipping enabled
2. create a payment intent
3. add a tip amount
4. inspect/log payment intent returned and see

"amountDetails": {
    "tip": {
      "amount": null
    }
  },

Expected behavior
I would expect the tip amount to be returned under amountDetails.tip.amount

Screenshots

Stripe Terminal React Native SDK version

• (e.g., ^0.0.1-beta.22)

Smartphone (please complete the following information):

• Device: Ipad 6th Gen
• OS: 17.7.1

Additional context
I was looking at the ios code here and I think this should be:

    class func mapFromAmountDetails(_ amountDetails: SCPAmountDetails?) -> NSDictionary {
        let amount: NSDictionary = [
            "amount": amountDetails?.tip?.amount ?? NSNull(),  // need to add  ?.amount
        ]

        let result: NSDictionary = [
            "tip": amount
        ]

        return result
    }
