Doctrine Join Many To Many without association - php

Question

I have: two entities with undirectional M:M association.
class ShareInfo
{
// ...
/**
* #ORM\ManyToMany(targetEntity="Item")
* #ORM\JoinTable(name="share_info_items",
* joinColumns={#ORM\JoinColumn(name="share_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="item_id", referencedColumnName="id")})
*
* #var Item[]
*/
private $items;
}
class Item
{
// ...
// This entity has no association with ShareInfo,
// because M:M is undirectional and defined in ShareInfo entity
}
What I want:
Select data from items table (Item entity), where at least one M:M record between Item and ShareInfo exists.
My suggestion which doesn't work (I've got a semantic error):
$queryBuilder
->select('i')
->from(Item::class, 'i')
->innerJoin(ShareInfo::class, 'shareInfo', 'WITH', 'shareInfo.items = i');
In pure SQL I'd do something like this:
SELECT i.*
FROM items i
INNER JOIN share_info_items shareInfo
ON shareInfo.item_id = i.id
Can't believe there is no DQL analog for this. The only solution I can imagine is to split undirectional M:M association into bi-directional
P.S. This question has no duplicates, I checked well.

The way to achieve this is through a subquery:
$em=$this->getDoctrine()->getManager();
$queryBuilder1=$em->createQueryBuilder();
$queryBuilder1->select(array('DISTINCT i.id'))
->from('AppBundle:ShareInfo', 'share_info')
->innerJoin('share_info.items', 'i');
$queryBuilder=$em->createQueryBuilder();
$queryBuilder->select('i')
->from('AppBundle:items', 'i')
->where($queryBuilder->expr()
->in('i.id',$queryBuilder1->getDql()));
