How to filter my shortcode?

Hello everyone.

I created a custom shortcode for my Vikinger theme that displays achievements with a filter for the type of achievement. I did it this way so that it displays using the existing theme template. However, I need it to display only the achievements that the user has and not all the achievements on the site. How can I do this?

Code:

/*
* Shortcode para Menu Mochila
*/

function my_achievements_shortcode( $atts ) {
  
// Recebe os atributos do shortcode
  $atts = shortcode_atts( array(
    'type' => 'mascotes',
    'id' => ''
  ), $atts );

  // Define a variável $achievement_type
  $achievement_type = $atts['type'];	

  // Exibe as conquistas
  $all_achievements = vikinger_gamipress_get_logged_user_achievements($achievement_type);

  // Define o número de itens por página
  $items_per_page = 12;

  // Obtém o número total de conquistas
  $total_items = count($all_achievements);

  // Calcula o número total de páginas
  $total_pages = ceil($total_items / $items_per_page);

  // Obtém o número da página atual
  $paged = isset($_GET[$atts['id']]) ? intval($_GET[$atts['id']]) : 1;

  // Define o início e o fim dos itens a serem exibidos na página atual
  $start = ($paged - 1) * $items_per_page;
  $end = $start + $items_per_page;

  // Define o link da paginação
  $page_link_base = add_query_arg($atts['id'], '', get_permalink());

  // Define os argumentos para a exibição das conquistas na página atual
  $achievement_args = [
	'user_points' => vikinger_gamipress_get_logged_user_points(),
    'achievement_complete_info' => false,
  ];

  if ($achievement_type === 'quest') {
    $achievement_args['achievement_image_wrap'] = true;
  }

  // Definir o número máximo de páginas a serem exibidas na paginação
$max_pages = 5;

// Exibe as conquistas da página atual
ob_start(); // inicia o buffer de saída
?>
<?php if (empty($all_achievements)) : ?>
    <p id="vazio">🪰 Tudo vazio por aqui, volte mais tarde.</p>
<?php else : ?>
<div class="grid grid-3-3-3-3 medium-space centered-on-mobile grid-stretched grid-items uniquegrid">
  <?php foreach (array_slice($all_achievements, $start, $items_per_page) as $achievement) :
      $achievement_args['achievement'] = $achievement;
      get_template_part('template-part/achievement/achievement', 'item-box', $achievement_args);
  endforeach; ?>
</div>
<?php endif; ?>
<?php if ($total_pages > 1) : ?>
<div class="pagination">

    <?php if ($paged > 1) { ?>
    <li>
      <a href="<?php echo add_query_arg($atts['id'], ($paged - 1), $page_link_base); ?>" class="prev">&laquo;</a>
    </li>
    <?php } ?>

    <?php
    $start_page = max(1, $paged - floor($max_pages / 2));
    $end_page = min($total_pages, $start_page + $max_pages - 1);

    for ($i = $start_page; $i <= $end_page; $i++) :
      // Adiciona o número da página à URL base
      $page_link = add_query_arg($atts['id'], $i, $page_link_base);
      ?>
      <li>
        <?php if ($paged === $i) : ?>
        <span class="current active"><?php echo $i; ?></span>
        <?php else : ?>
        <a href="<?php echo esc_url($page_link); ?>"><?php echo $i; ?></a>
        <?php endif; ?>

      <a href="<?php echo add_query_arg($atts['id'], ($paged + 1), $page_link_base); ?>" class="next">&raquo;</a>
    </li>
    <?php } ?>

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

  <?php
  return ob_get_clean(); // retorna o conteúdo do buffer de saída e limpa ele
}

add_shortcode( 'my_achievements', 'my_achievements_shortcode' );
