Include either name or slug in the include parameter using wp_list_categories?

I managed to figure this out with help from a friend. In case this helps anyone else, here’s my code.

<?php $sector_terms = array('animal-health', 'sustainability-science', 'technical-publishing');
$sector_ids = array_map( function( $sector_term )
{ $st = get_term_by('slug', $sector_term , 'post_tag'); return $st->term_id; }, $sector_terms); ?>

<?php $sector_args = array(
    'taxonomy' => 'post_tag',
    'show_count' => 0,
    'pad_counts' => 0,
    'title_li' => '',
    'include' => $sector_ids
); ?>

<ul>
    <?php wp_list_categories( $sector_args ); ?>
</ul>
