ManyToMany relationship only lets add from one side Symfony - php

Question

I'm a totally new Symfony user - I'm trying to make a ManyToMany relationship with User and Entity Group, however i can edit those only from one side(Group atm). Struggling with this for two days.. Would really appreciate some help. Here is my code..
Group Entity:
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=160)
*/
private $name;
/**
* #ORM\ManyToMany(targetEntity=Vartotojas::class, inversedBy="groups")
*/
private $users;
public function __construct()
{
$this->users = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
/**
* #return Collection|Vartotojas[]
*/
public function getUsers(): Collection
{
return $this->users;
}
public function addUser(Vartotojas $user): self
{
if (!$this->users->contains($user)) {
$this->users[] = $user;
$user->addGroup($this);
}
return $this;
}
User Entity:
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=64)
*/
private $name;
/**
* #ORM\ManyToMany(targetEntity=Grupe::class, inversedBy="users")
*/
private $groups;
public function __construct()
{
$this->groups = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
/**
* #return Collection|Grupe[]
*/
public function getGroups(): Collection
{
return $this->groups;
}
public function addGroup(Grupe $group): self
{
if (!$this->group->contains($group)) {
$this->groups[] = $group;
$group->addUser($this);
}
return $this;
}
I'm using EasyAdmin to manage those, and my Group/User crud's are the same like this:
namespace App\Controller\Admin;
use App\Entity\Grupe;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;
use EasyCorp\Bundle\EasyAdminBundle\Field\TextField;
use EasyCorp\Bundle\EasyAdminBundle\Field\AssociationField;
class GrupeCrudController extends AbstractCrudController
{
public static function getEntityFqcn(): string
{
return Grupe::class;
}
public function configureFields(string $pageName): iterable
{
return [
TextField::new('name'),
AssociationField::new('users'),
];
}
}

if you want to edit a user inside the Group admin, I think what you are looking for is the CollectionField, this works with a Symfony form created by you.
