Hello good day, I have a classic payment app and it works perfectly, but when a user uses lucky patcher they can buy items without having to pay, is there a way to avoid this from lucky patcher? I attach my kotlin code so that you have an idea of what any other questions are about internally

`private val purchaseUpdateListener = PurchasesUpdatedListener { billingResult, purchases ->
          when {
              billingResult.responseCode == BillingClient.BillingResponseCode.OK && !purchases.isNullOrEmpty() -> {
                  for (purchase in purchases) {
                      if (purchase.purchaseToken.isNullOrEmpty()) {
                          // The payment was made in cash, it must be handled according to your requirements
                          // You can display a message to the user or perform some specific action
                          Query_Version25() // Call the QueryVersion25() function for cash payments
                      } else {
                              idp = purchase.orderId
                              Query_Version8()
                              Query_Version9()
                              isProductPurchased = true
                      }
                  }
              }
              billingResult.responseCode == BillingClient.BillingResponseCode.USER_CANCELED -> {
                  Toast.makeText(this, R.string.ms27, Toast.LENGTH_SHORT).show()
              }
              else -> {
                  Toast.makeText(this, R.string.ms28, Toast.LENGTH_SHORT).show()
              }
          }

          if (isProductPurchased) {
              // Reset the variable to allow the user to buy the same product again
              isProductPurchased = false
          }
      }`
