Woocommerce - Display categories within the loop

[admin]

Is it posible to display the <em>product categories</em> right beneath the tile, within the WooCommerce loop?

Here's a code that I've included in

mytheme/woocommerce/content-product.php

, taken from the <a href="https://codex.wordpress.org/Function_Reference/get_the_category" rel="nofollow">Wordpress documentation on

get_the_category()

</a>; yet it doesn't seem to output anything at all

        <a href="<?php the_permalink(); ?>" class="titulo-insumo" title="<?php the_title(); ?>">
            <?php the_title(); ?>
        </a>
        <div class="label-group"><!--Categories *should* be outputed here -->
        <?php
        $categories = get_the_category();
        $separator = ' ';
        $output = '';
        if($categories){
                foreach($categories as $category) {
                        $output .= '<a href="'.get_category_link( $category->term_id ).'" class="label bg-terciary" title="' . esc_attr( sprintf( __( "Ver todos los artículos en la categoría %s" ), $category->name ) ) . '">'.$category->cat_name.'</a>'.$separator;
                }
        echo trim($output, $separator);
        }

        ?>

        </div>
