Symfony 4 Add ManyToMany Entity trough FORM - php

Question

I am heavily stuck on problem with inserting data trough html.twig when passing one Entity to the other. I am able to add or edit single entities but i cant figure out how to handle adding relations.
Tournament Entity class - unimportant stuff deleted

I am able to edit tournament or team data trough forms and save it to database.
What I am not able is to add data into this relation.
Form Class for this
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('team', EntityType::class, array(
'class' => Team::class,
'multiple' => true,
'expanded' => true,
))
->add('Add Team', SubmitType::class);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Tournament::class
]);
}
Tournament Controller method addTeam - should add Team Entity into Trounament teams collection
/**
* #param Team $team
* #param Request $request
* #Route("/addTeamToEvent/{idTournament}",name="addTeamToEvent")
* #return RedirectResponse|\Symfony\Component\HttpFoundation\Response
*/
public function addTeam(Tournament $tournament, Request $request)
{
$form = $this->createForm(TeamToEvent::class, $tournament);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$this->entityManager->persist($tournament);
$this->entityManager->flush();
return new RedirectResponse($this->router->generate('welcome'));
}
return $this->render('welcome/addTeamToEvent.html.twig', ['form' => $form->createView()]);
}
What should be the right aproach? I am totaly lost and i don't know how to do this.
