Is consumePurchase = false meaningful in CodelessIAP?

Is consumePurchase = false meaningful in CodelessIAP? If consumePurchase = false, the return value of ProcessPurchase is PurchaseProcessingResult.Pending, but IAPListner and IAPButton do not find a function that explicitly calls ConfirmPendingPurchase. Does consumePurchase = false make sense? Thank you in advance.
