I'm new to WP and I want to list all unique authors that have posts in category on the page.

My code (location: wp-content/themes/custom-theme/category.php)

<div class="container">
                <div class="row">
                        <?php

                        if ( have_posts() ) : ?>
 
                        <?php while( have_posts() ) : the_author(); ?>
                        <div class="col-md-2 text-center">
                            <?php the_author_meta( 'display_name', 30 ); ?>
                        </div>
                        <?php endwhile; ?>

                        <?php else: ?>

                            <p class="text-center">No authors</p>

                        <?php endif; ?>
                 </div>
</div>

This is not giving expected result, can someone help me?

Thanks.
