magento2 – Add description to Related Products

I try to add product Short Description in the Related Products section in Magento 2.4 version.

I overwrite this file:/app/design/frontend/Theme/MyTheme/Magento_Catalog/templates/product/list/items.phtml in my custom theme and I add the following code:

<?=/* @noEscape */ $_helper->productAttribute($item, $item->getShortDescription(), 'short_description')?>

The code work only for Simple Products if there in the related products are some configurable products the code is not return anything.

Is there any way to have the short description for both types of products?

Thank you
