Be careful with ChatCPT codes, they are sometimes incorrect. You are welcome to share the snippet. And also set the topic to done when it is finished for you.

Yes, I know, but it worked out of the box so to speak! ??

Here is the snippet, I have added it to my-custom-code.php

// Modified category widget
// Function to define and register the custom widget
function initialize_custom_wc_widget() {
// Define the custom widget class
class Custom_WC_Product_Categories_Widget extends WP_Widget {

    public function __construct() {
        parent::__construct(
            'custom_wc_product_categories',
            'Custom WC Product Categories',
            array('description' => 'Displays product categories with custom functionality.')
        );
    }

    public function widget($args, $instance) {
        // Start widget output
        echo $args['before_widget'];

        // Display widget title
        if (!empty($instance['title'])) {
            echo $args['before_title'] . $instance['title'] . $args['after_title'];
        }

        // List all main categories
        $main_category_args = array(
            'taxonomy' => 'product_cat',
            'hide_empty' => 1,
            'parent' => 0
        );
        $main_categories = get_categories($main_category_args);
        foreach ($main_categories as $cat) {
            echo '<a href="' . get_term_link($cat->term_id) . '">' . $cat->name . '</a><br>';

            // Get the current category
            $current_cat = get_queried_object();

            // If we are on a category page and it's the current main category or one of its subcategories, list subcategories
            if (isset($current_cat->term_id) && $current_cat->taxonomy == 'product_cat') {
                if ($current_cat->term_id == $cat->term_id || $current_cat->parent == $cat->term_id) {
                    $this->list_sub_categories($cat->term_id, $current_cat);
                }
            }
        }

        // End widget output
        echo $args['after_widget'];
    }

    // Recursive function to list subcategories
    private function list_sub_categories($parent_id, $current_cat, $level = 1) {
        $sub_category_args = array(
            'taxonomy' => 'product_cat',
            'hide_empty' => 1,
            'parent' => $parent_id
        );
        $sub_categories = get_categories($sub_category_args);
        foreach ($sub_categories as $sub_cat) {
            echo '<div style="margin-left: ' . (20 * $level) . 'px;"><a href="' . get_term_link($sub_cat->term_id) . '">' . $sub_cat->name . '</a></div>';

            // If we are on a category page and it's the current subcategory or one of its subcategories, list its subcategories
            if ($current_cat->term_id == $sub_cat->term_id || $current_cat->parent == $sub_cat->term_id) {
                $this->list_sub_categories($sub_cat->term_id, $current_cat, $level + 1);
            }
        }
    }

    public function form($instance) {
        // Add form fields for widget settings if needed
    }

    public function update($new_instance, $old_instance) {
        // Add update logic for widget settings if needed
        return $new_instance;
    }
}

// Register the custom widget
register_widget('Custom_WC_Product_Categories_Widget');}

// Add an action to run our function when widgets are initialized
add_action('widgets_init', 'initialize_custom_wc_widget');
