How to display products by category on the catalog page?

Question

WordPress

Displaying products by category on the catalog page. It is necessary that the name of the category would first go, then the products of this category. I don't know how to implement this functionality.
I would implement everything using shortcodes, but then the ajax filter through the plugin does not work. It works, of course, but it already redirects to the same page ... Thank you.

<?php
        // параметры по умолчанию
        $args = array(
          'numberposts' => 4, // Число постов
          'category_name'    => 'name', // Имя категории
          'order'       => 'DESC',
          'post_type'   => 'post'
        );
        $posts = get_posts($args);

        foreach($posts as $post){ setup_postdata($post);?>

            <div class="post_item">
                                        <?php the_content(); ?>
            </div>

        <?php }
          wp_reset_postdata();
        ?>
