ManyToMany with the same entity

[pinoinside]

Describe the bug
I have a table "people" and a join-table to set relationships between people (so it's a many-to-many with the same entity) with extra data. I created the join-table CRUD controller and it works as expected, but if I add a collection field inside people to add the relationships while editing a single people, when I save it sets the same record on both fields of the many to many record.

To Reproduce
Symfony 6.4 - EasyAdmin 4
