How to display custom taxonomies and their terms

I created Custom Post Types and taxonomies for them on the site. I need to list these taxonomies and their terms. How can i do this? For example, I created two , one for taxonomies, and the second for terms

function pediatric_create_post_type() {
  register_post_type( 'speakers', 
      array(
        'labels' => array(
        'name' => __( 'Speakers' ),
        'singular_name' => __( 'Speaker' ),
      ),
       'public' => true,
       'has_archive' => true,
       'supports' => array( 'thumbnail', 'title', 'editor' ),
      )
  );    
    
  register_taxonomy(
  'positions',
  'speakers',
      array(
      'label' => ( 'Positions' ),
      'hierarchical' => true,
      )
  );
    
  register_taxonomy(
  'countries',
  'speakers',
      array(
      'label' => ( 'Countries' ),
      'hierarchical' => true,
      )
  );
}
add_action( 'init', 'pediatric_create_post_type' );
<div class="speakers-filter">
  <ul class="speakers-tax">
    <li></li>
  </ul>
  <ul class="speakers-tax_terms">
    <li></li>
  </ul>
</div>
