Custom routes adding isOpen()

1

Is there any way I can pass isOpen() with custom routes?

My route code

<?php

Kirby::plugin('mg/routes', [
    'routes' => [
      [
        'pattern' => 'team/(:any?)',
        'action'  => function($arguments) {
          $arguments = $this->arguments();

          return page('subpage/team')->render([
            'arguments' => $arguments,
          ]);
        },
      ],
    ],
    'controllers' => [
      'team' => function ($kirby, $site, $page, $arguments) {

        $person = page('subpage/seminare')->index()->findBy('slug', $arguments[0]);

        return [
          'person' => $person
        ];
      },
    ],
  ],
);

In my navigation template

<?php if($item->slug() == 'team'): ?>
        <?php $children = page('subpage/seminare')->children()->template("contactperson")->listed(); ?>
          <ul>
            <?php foreach($children as $child): ?>
              <li><a<?php e($child->isOpen(), ' class="Selected mm-listitem mm-listitem--selected"') ?> href="<?= $item->url() ?>/<?= $child->slug() ?>"><?= $child->title()->html() ?></a></li>
            <?php endforeach ?>
          </ul>
