Answer 1

Its worked for me
$qb = $em->createQueryBuilder();
$query = $qb->select('chats, user')
->from('Chat\Entity\Chat', 'chats')
->join('chats.user', 'user')
->join('chats.user', 'user2')
->where('user.id = :user AND user2.id = :inv ')
->setParameter('user', <User1.id>)
->setParameter('inv',<User2.id>)
->setMaxResults(1)
->getQuery();
