        if (purchase) {
          if (!Array.isArray(purchase)) {
            // Handle the purchase being updated
            await finishTransaction({ purchase, isConsumable: false });
            setTransactionId(purchase.originalTransactionIdentifierIOS ?? null); // Sets the transactionId to a float value
          }
        }
      })
      .catch((error) => {
        console.log(error);
