newDeferredPaymentRequest doesn't work

Hi all Im trying to update deferDeferredPaymentRequest on event completeShippingMethodSelection API ver 14 So Im using ApplePayShippingMethodUpdate object which contains newDeferredPaymentRequest

But deferred payment cannot be updated. Here is my ApplePayDeferredPaymentRequest object for newDeferredPaymentRequest:

            "deferredBilling": {
                "label": "Pay for Later",
                "amount": 68,
                "paymentTiming": "deferred",
                "type": "final",
                "deferredPaymentDate": "2024-01-25"
            },
            "managementURL": "https://siteURL.com",
            "paymentDescription": "A description of the deferred payment to display to the user in the payment sheet.",
            "freeCancellationDate": "2024-01-25",
            "freeCancellationDateTimeZone": "America/New_York"
        }

Even I tried to put mistake for newDeferredPaymentRequest but ApplePay doesn't throw a JS error

Can we update deferred ?

for example, ApplePayRecurringPaymentRequest can't be updated according to documentation https://developer.apple.com/documentation/apple_pay_on_the_web/applepayrecurringpaymentrequest

But I can't find same info for Deferred.

Who can help me with it?
