How to add a class to an element of the current WordPress category?

Question

WordPress

Good afternoon
Help me please, otherwise I'm slowing down

The usual code that displays the categories of the store in the a tag and the number of products in it
Displayed on the general page of the store and in the categories

Tell me how to add the "current-cat" class to the current category?
For example, if you moved to the "food" category so that one of the links could be highlighted.

I think for example:
Get the current title of the category page:

$current_cat = $category_title = single_term_title('', 0);

and then we compare it with the one in the a tag,
or it's not there anymore .. confused

How to write the condition correctly?

<div class="categories">
  <?php $product_categories = get_terms(array( 'taxonomy' => 'product_cat', 'hide_empty' => true) );
  
      if( $product_categories ) : ?>
        <?php foreach( $product_categories as $product_category ) : ?> 
        
          <a href="<?php echo get_term_link( $product_category ) ?>">
            <?php echo $product_category->name ?>
            <span><?php echo $product_category->count ?></span> 
          </a>
          
        <?php endforeach; ?>
      <?php endif; ?>
</div>

echo is_tax() && get_queried_object()->slug === $product_category->slug ? 'current' : '';
