Removing sidebar from single product page in FACTORY wp theme

I want to disable the sidebar completely from WooCommerce single product page, and make the page full width.

I have read and tried each and every document available but to nothing is available.

Steps:

1. Copied the following code to functions.php

   function remove_sidebar_shop() {
       if ( is_product() ) {
           remove_action('woocommerce_sidebar','woocommerce_get_sidebar');
           echo("Test if");
       }
   
       else {
           echo("Test else");
       }
   }
   
   add_action('get_header','remove_sidebar_shop');
   
   

(the echo parts were for debugging)

2. Commented the get_sidebar(); part from archive-product.php after copying it to my-theme/woocommerce.

3. Commented the get_sidebar(); part from single-product.php after copying it to my-theme/woocommerce.

4. Commented the whole sidebar.php file.

But nothing seems to work.
