What's the best way to display pagination on a custom post type archive page without a plugin? I tried paginate_links() didn't work.

I'm using a custom query and here's the code:

$args = [
    'post_type'   => 'on_my_mind',
    'post_status' => 'publish',
];
$omm  = new WP_Query($args); ?>

<?php if ($omm->have_posts()): while ($omm->have_posts()): $omm->the_post(); ?>
    <?php get_template_part('template-parts/content', 'on_my_mind') ?>
<?php endwhile; ?>
<?php endif; ?> 
<?php wp_reset_postdata(); ?>
