integration a class WC_Admin_Duplicate_Product and royal addon Woo Grid

Hi, I want to extent the functionality of a plugin called “Royal addons” and it’s module woogrid. 

WooGrid module helps to display woocommerce product in elementor builder in various ways. I want to extent “manual selection” part, so that after selecting a product it creates a duplicate of that product in woocommerce (via build-in class [WC_Admin_Duplicate_Product](https://woocommerce.github.io/code-reference/classes/WC-Admin-Duplicate-Product.html)). 

And after selection, it will display the duplicated product So, to do the mentioned above duplication , I

 need to add a function that duplicates a product using woocommerce class WC_Admin_Duplicate_Product – here is it 

public function duplicate_selected_products( $selected_products ) {

if ( empty( $selected_products ) || ! class_exists( 'WC_Admin_Duplicate_Product' ) ) {

return [];

}

$duplicated_products = [];

foreach ( $selected_products as $product_id ) {

$duplicate_product = new WC_Admin_Duplicate_Product();

$new_product_id = $duplicate_product->product_duplicate( $product_id );

if ( $new_product_id ) {

$duplicated_products[] = $new_product_id;

}

}

return $duplicated_products;

    }

And the problem is that When I add this function to the file with woogrid module (called wpr-woo-grid.php) WordPress doesn’t access the woocommerce class

it shows an error Fatal error: Uncaught Error: Class WprAddons\Modules\WooGrid\Widgets\WC_Admin_Duplicate_Product’ not found in /home/winecard/public_html/wp-content/plugins/royal-elementor-addons/modules/woo-grid/widgets/wpr-woo-grid.php

I tried to use there requests with location of origial file 

require_once ‘/home/winecard/public_html/wp-content/plugins/woocommerce/include/admin/class-wc-admin-duplicate-product.php’; 

require_once WP_PLUGIN_DIR . ‘/woocommerce/includes/admin/class-wc-admin-duplicate-product.php’; 

require PATH_THIRD . ‘woocommerce/woocommerce.php’; 

I used this  $duplicate_product = new WooCommerce\Admin\WC_Admin_Duplicate_Product();

instead of this $duplicate_product = new WC_Admin_Duplicate_Product();  

How could I access the class woocommerce at royal addons plugin? thank you for your reply!
