Twing and Controller on symfony

Symfony has a "private" form for working with forms.

Basically it is built into the Controller and then needs to be started in Twig.

2 Create the form with the fields you want to return.

3 ° Start and manipulate the form as you wish on Twig.

There is a very clear example of how you can do this in the documentation:
