Symfony Doctrine Count ManyToMany Relationship

I have an User entity with a many-to-many entity (Wish) linked to it, I now need the top 10 wishes now using the Symfony QueryBuilder.

The problem here is that i do not have direct access to the ManyToMany Table/Entity/Repository as its automatically created and managed by Doctrine ORM.

Making a manual OneToMany, ManyToOne Entity is not really an option as it will break existing code (mostly the automatic collection population and the add / remove functions of it)

Doing a manual SQL is kinda dodgy since the table name is generated and might change some update (even if not I would prefer to keep it clean)

some code:

class User {
// .........
 /**
 * @ORM\ManyToMany(targetEntity="App\Entity\Wish")
 */
private $wish;

public function __construct()
{
    $this->wish = new ArrayCollection(); // with get/set/add/remove etc
}
}


class Wish {
/**
 * @ORM\Id()
 * @ORM\GeneratedValue()
 * @ORM\Column(type="integer")
 */
private $id;

/**
 * @ORM\Column(type="string", length=255)
 */
private $name;
// ... get set etc
}
