Set cookie inside webform handler

Question

Following up with my previous question, I need to set and retrieve a cookie in two difference places:

• set - inside postSave() in a Webform handler
• get - inside an event subscriber.

In looking around, it seems that there are a few different options for tools, such as \Symfony\Component\HttpFoundation\Response and \Symfony\Component\HttpFoundation\Cookie, or GuzzleHttp\Cookie\SetCookie and GuzzleHttp\Cookie\CookieJar.

For setting the cookie, if I try this in my webform handler:

$values = $webform_submission->getData();

$response = new Response();
$cookie = new Cookie('Dixon customer info form', $values['destination_url'], 0, '/' , NULL, FALSE);
$response->headers->setCookie($cookie);
$response->send();

I get redirected to a blank page. If I try this:

$values = $webform_submission->getData();

$cookie_jar = new CookieJar();
  // Get the current host.
  $host = \Drupal::request()->getSchemeAndHttpHost();

  // Set a cookie for the specific form.
  $cookie = new SetCookie([
    'Name' => 'formEnterCookie',
    'Value' => $values['destination_url'],
    'Domain' => $host,
    'Secure' => FALSE,
  ]);
  $cookie_jar->setCookie($cookie);

no cookie gets set. Using either option, how do I set my cookie within my webform handler?

Just in case someone still needs this: There's a module https://github.com/vaza18/webform_cookie, which work fine for me. It's setting a cookie the old way - using PHP https://www.php.net/manual/en/function.setcookie.php function.
