I wonder if it wasn't better to use the NativeSessionTokenStorage to not depend on the HttpFoundation component here.

Never mind, we already have this above.

$csrfManager = new CsrfTokenManager($csrfGenerator, $csrfStorage);

// add the FormExtension to Twig
$twig->addExtension(
new FormExtension(new TwigRenderer($formEngine, $csrfProvider))
new FormExtension(new TwigRenderer($formEngine, $csrfManager))
);

// create your form factory as normal
