How to create two connected radio lenses?

Question

In the code below, 2 radio exchanges are created, however they are not connected to each other. One is displayed with a name description_form[friend], and the other with a name - description_form[guide]. How can they be displayed with the same name? The documentation is not clear on this.

public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('friend', RadioType::class, array(
                'label'    => 'Friend',
                'required' => false
            ))
            ->add('guide', RadioType::class, array(
                'label'    => 'Guide',
                'required' => false
            ));
    }

Using a list is RadioTypenot so simple, so everyone recommends you use ChoiceTypeone that dynamically creates a list of radio depending on the array of data of choice.
