How to display products from categories and subcategories in woocommerce?

Question

WooCommerce

Good evening.
There are categories and subcategories for both products.

You need to display the name of the category and if it has subcategories, then display them and then the products from this subcategory.
5 products from each category.
It should look like this
Category
Product Product Product
Category
Subcategory
Product Product Product
Subcategory
Product Product Product
Category
Product Product Product
Here's the code I wrote, but I can't put the subcategories in the category.

$taxonomy = 'product_cat';
$orderby = 'name';
$show_count = 0;      // 1 for yes, 0 for no
$pad_counts = 0;      // 1 for yes, 0 for no
$hierarchical = 1;      // 1 for yes, 0 for no
$title = '';
$empty = 1;

$args = array(
    'taxonomy' => $taxonomy,
    'orderby' => $orderby,
    'show_count' => $show_count,
    'pad_counts' => $pad_counts,
    'hierarchical' => $hierarchical,
    'title_li' => $title,
    'hide_empty' => $empty
);
$all_categories = get_categories($args); ?>

<?php foreach ($all_categories as $cat): ?>
    <?php if ($cat->category_parent == 0): ?>
        <h2 class="products-section__title"><?php echo $cat->name; ?></h2>
        <div class="bs-products-loops">
                                  <?php
                                  $products = new WP_Query([
                                  'post_type' => 'product',
                                  'posts_per_page' => 5,
                                  'product_cat' => $cat->slug
                                  ]);
                                  ?>
                                  
                                  <?php if ($products->have_posts()): ?>
                                  
                                  <?php while ($products->have_posts()): ?><?php $products->the_post(); ?>
                                  
                                  <?php do_action('woocommerce_product_loop_start'); ?>
                                  
                                  <?php wc_get_template_part('content', 'product'); ?>
                                  
                                  <?php do_action('woocommerce_product_loop_end'); ?>
                                  
                                  <?php endwhile; ?><?php wp_reset_postdata(); ?>
                                  
                                  <?php endif; ?>

                <h3><?php echo $sub_category->name; ?></h3>
                <div class="bs-products-loops">

                    <?php if ($products->have_posts()): ?>

                                                          <?php do_action('woocommerce_product_loop_start'); ?>

            <?php endforeach; ?>

        <?php endif; ?>
    <?php endif; ?>
<?php endforeach; ?>

Tell me, where am I wrong?
Thanks in advance.
