Short Code is not working

Hello Guys,

wanted to add following code to short coder Plugin, but its not working:

——————–
function displayProductName($item) {
$productName = get_the_title($item[‘id’]);
return $productName;
}

add_shortcode(‘product_name’, ‘displayProductName’);
——————-

Code should disdplay title of WOO product with id=”XYZ”

Used following shortcode: [sc name="woo_get_productname" id="8876"]

“woo_get_productname” was my given name in short coder.

Using Guntener Business Theme and Elementor Pro.

Thxs for your help, Markus
