How to work with ManyToManyField Django?

Question

Django

How to get a choice from one to several Contractors (owner) from the "Technical support" group, in the selection field in the application in the admin panel.
Now I can set it up only to receive one, and no more, performers.
Used ForeignKey:

class Application(models.Model):
    ...
    owner = models.ForeignKey(User, null = True, blank = True, limit_choices_to={ 'groups__name': 'Техническая поддержка'})

After reading, I realized that you can get them through ManyToManyField, and did the following:

class Owner(models.Model):
    executor = models.ForeignKey(User, null = True, blank = True, limit_choices_to={ 'groups__name': 'Техническая поддержка'})


class Application(models.Model):
    ...
    owner = models.ManyToManyField(Owner, verbose_name = 'Исполнитель')

But, the executor is taken not from the "Technical support" group, but from the "executor", which still needs to be created. And even if you create, the choice will be as follows:

In general, I just can’t figure it out. Many thanks to all those who try to help with this problem.

I don’t know what kind of fields you have there in the model, but here is an example:

class Owner(models.Model):
    name = models.CharField(max_length=50)

    def __str__(self):
        return '{0}'.format(self.short_name)
