How add a class to a label element with Symfony forms?

Question

I have a FormBuilderwith Symfony3 and I need you to add a class to the discount label. How can you observe the third parameter of the add method is an array and a key is attr which has another array with the attributes of the input element, but not the label.

How can I add class to the label?

 $builder
->add('note', TextareaType::class, array(
    'label' => "Notes",
    'required' => false
))
->add('discount', NumberType::class, array(
    'required' => false,
    'attr' => array(
        'class' => "hidden"
    )
))

You can see the label_attr parameter in symfony docs

'label'=>"Notes,array('label_attr' => array('class' => 'class_name'))"

This is what worked for me in Symfony 5.4 : 'label_attr' => ['class' => 'your-label-classes']

Example:

class YourFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
       $builder
            ->add('email', EmailType::class, [
                'label'=>'Your label name',
                'label_attr' => ['class' => 'your-label-classes', 'for'=>"email"],
                'attr' => [
                    'class' => "your-field-classes",
                    'type' => "email",
                ],
            ])
            ...
    }
    ...
}
