Show the relevant category when view a product

Hello,

We need your support for the following purpose:

When access or viewing a Woo product, show a popup that contain a clickable product category, so that we can show message like this way:

FIND more similar product in the following category

I asked a Chatgpt to provide a code snippet and put [product_categories] in the popup content to achieve the above purpose, but it always show all of categories in Popup.

Here are the code snippets that I already tried:

// Create a shortcode to display product categories with clickable links
function display_product_categories() {
    global $product;

    if ( is_product() ) {
        // Get the product categories as clickable links
        $categories = wc_get_product_category_list( $product->get_id(), ', ', '<p class="posted_in">', '</p>' );

        // Return the categories if they exist
        if ( $categories ) {
            return $categories;
        }
    }

    return ''; // Return nothing if not on a product page
}
add_shortcode( 'product_categories', 'display_product_categories' );

// Create a shortcode to display product categories with clickable links
function display_product_categories() {
    global $product;

    if ( is_product() ) {
        // Get the product categories as clickable links
        $categories = wc_get_product_category_list( $product->get_id(), ', ', '<p class="posted_in">', '</p>' );

        // Return the categories if they exist
        if ( $categories ) {
            return $categories;
        }
    }

    return ''; // Return nothing if not on a product page
}
add_shortcode( 'product_categories', 'display_product_categories' );

// Create a shortcode to display specific categories of the current product
function display_specific_product_categories() {
    if ( is_product() ) {
        global $post;
        
        // Get the product object from the post ID
        $product = wc_get_product( $post->ID );

        // Ensure we are working with a valid product
        if ( $product ) {
            // Get the categories of the current product as clickable links
            $categories = wp_get_post_terms( $product->get_id(), 'product_cat', array( 'fields' => 'all' ) );

            if ( ! empty( $categories ) && ! is_wp_error( $categories ) ) {

    }

    return ''; // Return nothing if not on a product page
}
add_shortcode( 'product_categories_debug', 'display_specific_product_categories_debug' );

As show above, I have a tried lots of code snippet, but all failed.

Could you please show workable code snippet please?

Thanks in advance.
