Need Help

Can I override the models of acl acos?
What do I have to put in the table and entity classes so that it doesn’t give me the exception AclNode::node() - Couldn’t find Acos node identified by "Array
(
[Acos0.model] => MyAcos
[Acos0.foreign_key] => 8
)
"
when I try to allow and aco for an aro?
This is the code for the action permissions in GroupsController:

    public function permissions()
    {
		$this->loadModel('MyAcos');
        if ($this->request->is(['post'])) {
			$group = $this->Groups->get($this->request->getData('group_id'));
			$aco = $this->MyAcos->get($this->request->getData('aco_id'));
			$this->Acl->allow($group, $aco);
			
			return $this->redirect(['action' => 'index']);
        }
		$acos = $this->MyAcos->find('list', ['limit' => 200])->order('id');
		$groups = $this->Groups->find('list', ['limit' => 200]);
		$this->set(compact('acos', 'groups'));
    }

This is the code for permissions.php template:

<?php
/**
 * @var \App\View\AppView $this
 * @var \App\Model\Entity\User $user
 * @var \Cake\Collection\CollectionInterface|string[] $groups
 * @var \Cake\Collection\CollectionInterface|string[] $enterprises
 */
?>
<div class="row">
    <aside class="column">
        <div class="side-nav">
            <h4 class="heading"><?= __('Acciones') ?></h4>
            <?= $this->Html->link(__('Listar Grupos'), ['action' => 'index'], ['class' => 'side-nav-item']) ?>
        </div>
    </aside>
    <div class="column-responsive column-80">
        <div class="users form content">
            <?= $this->Form->create() ?>
            <fieldset>
                <legend><?= __('Crear permisos') ?></legend>
                <?php
                    echo $this->Form->control('group_id', ['label' => 'Grupo', 'options' => $groups, 'empty' => '- Seleccione un grupo -']);
                    echo $this->Form->control('aco_id', ['label' => 'Control de acceso', 'options' => $acos, 'empty' => '- Seleccione un control de acceso -']);
                ?>
            </fieldset>
            <?= $this->Form->button(__('Crear')) ?>
            <?= $this->Form->end() ?>
        </div>
    </div>
</div>

This is the code for MyAcosTable.php:

<?php
declare(strict_types=1);

namespace App\Model\Table;

use Acl\Model\Table\AcosTable;

class MyAcosTable extends AcosTable
{
    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config): void
    {
        parent::initialize($config);

        $this->setDisplayField('alias');
    }
}

And this is the code for MyAcos.php:

<?php
declare(strict_types=1);

namespace App\Model\Entity;

use Acl\Model\Entity\Aco;

class MyAcos extends Aco
{
	public function bindNode($user) {
		return ['model' => 'Groups', 'foreign_key' => $user['Users']['group_id']];
	}
}

I found out what was the problem, I was passing the object aco but had to pass the string controllers/controller/action
