How to get a trade offer certificate?

Question

1C-Bitrix

On the detailed page of the product card, I need to separately receive and display the property of the trade offer in the right separate place. Every trade offer has a "barcode" property and I can't get it.
Thus, I receive only from the main product card.

<?//=$arResult['PROPERTIES']['НАЗВАНИЕ_СВОЙСТВА']['DISPLAY_VALUE'];?>

And I want to receive from the trade offer, so that later, depending on the selected offer, the barcode also changes dynamically. Tell me how can this be done?
