show caution text if customer insert larger quantity

Question

If a customer inserted a quantity that is larger than the quantity of selected store echo text below the input type [qty] that says "The requested qty is larger than the quantity on this selected store".

The below code get the total quantity

  public function getStockStatus()
    {
        $productId = $this->getCurrentProduct()->getId();
        /** @var StockItemInterface $stockItem */
        $stockItem = $this->stockRegistry->getStockItem($productId);
        $isInStock = $stockItem ? $stockItem->getIsInStock() : false;
        return $isInStock;
    }

I have Attributes [USA &NZD] that have same name as my store views and below code get the values on those attributes and show alert if the attribute have value of 0.

how to apply similar logic but if the customer insert larger qty and click add to cart button a text message show on screen.

logic : if (StoreAttributes[USA or NZD] < QTY inserted){ echo popup } else{ continue;}
