I am trying to add the script to the particular Product Category page, but the code is not adding it to the category.

Page (working):

function wpb_hook_faq_javascript() {
  if (is_single ('8') || is_page ('8')) { 
    ?>
    <script type="application/ld+json">

    </script>

 <?php }
}
add_action('wp_footer', 'wpb_hook_faq_javascript');

Product Category (not working):

function wpb_hook_faqtocategory_javascript() {
  if ( in_category( 'category-name' )) { 
    ?>
    <script type="application/ld+json">

    </script>

 <?php }
}
add_action('wp_footer', 'wpb_hook_faqtocategory_javascript');

But the above code is not working.

Product Category URL:

wp-admin/term.php?taxonomy=product_cat&tag_ID=9&post_type=product
