Webform Create node, send email when webform is submitted

I'm creating a node when a webform is submitted and adding the webform submission id to an int field on the node so the node is linked to the webform submission. I'm also sending an email when the webform is submitted.

Here's the node creation handler code.

<?php

namespace Drupal\my_module\Plugin\WebformHandler;

use Drupal;
use Drupal\Core\Form\FormStateInterface;
use Drupal\node\Entity\Node;
use Drupal\webform\Plugin\WebformHandlerBase;
use Drupal\webform\webformSubmissionInterface;

/**
 * Create Award Nominee nodes from a webform submission.
 *
 * @WebformHandler(
 *   id = "award_nominee_from_webform",
 *   label = @Translation("Award Nominee node"),
 *   category = @Translation("Webform"),
 *   description = @Translation("Creates an Award Nominee node."),
 *   cardinality = \Drupal\webform\Plugin\WebformHandlerInterface::CARDINALITY_UNLIMITED,
 *   results = \Drupal\webform\Plugin\WebformHandlerInterface::RESULTS_PROCESSED,
 *   submission = \Drupal\webform\Plugin\WebformHandlerInterface::SUBMISSION_REQUIRED,
 * )
 */

class AwardNomineeWebformHandler extends WebformHandlerBase {

  /**
   * {@inheritdoc}
   */
  public function submitForm(array &$form, FormStateInterface $form_state, WebformSubmissionInterface $webform_submission) {
    $webform = $webform_submission->getWebform();
    // Get an array of form field values.
    $submission_array = $webform_submission->getData();
    // Todo: Prevent this save from sending emails.
    $webform_submission->save();

    $sid = $webform_submission->id();

    $term = \Drupal::entityTypeManager()
      ->getStorage('taxonomy_term')
      ->load($submission_array['nomination_award']);
    $award_name = $term->getName();

    if (empty($submission_array['member_information'])) {
      $nominee_middle_name = !empty($submission_array['nominee_middle_name']) ? ' ' . $submission_array['nominee_middle_name'] . ' ' : ' ';
      $title = $submission_array['nominee_first_name'] . $nominee_middle_name . $submission_array['nominee_last_name'];
      $nominee_accomplishments = $submission_array['nominee_accomplishments'];

      $this->getNode($title, $award_name, $nominee_accomplishments, $sid);
    }
  }

  /**
   * Creates the node when it's a new webform submission.
   *
   * @param string $title
   * @param string $award_name
   * @param mixed $nominee_accomplishments
   * @param int $sid
   *
   * @return void
   * @throws \Drupal\Core\Entity\EntityStorageException
   */
  protected function getNode(string $title, string $award_name, mixed $nominee_accomplishments, int $sid): void {
    $node = Node::create([
      'type' => 'award_nominee',
      'status' => FALSE,
      'title' => $title,
      'field_award_nominee_plaque_name' => '',
      'field_award_nominee_award_name' => $award_name,
      'field_award_nominee_organization' => '',
      'field_award_nominee_members' => '',
      'body' => [
        'value' => $nominee_accomplishments,
        'format' => 'bold_italic',
      ],
      'field_webform_submission_id' => $sid,
      'field_award_nominee_city' => '',
      'field_award_nominee_state' => '',
    ]);
    $node->save();
  }

}

There's even a hook to delete the nodes when the submission is deleted. Here's the hook:

/**
 * Implements hook_webform_submission_delete().
 */
function my_module_webform_submission_delete(WebformSubmissionInterface $webform_submission) {
  $entity_ids = Drupal::entityQuery('node')
    ->condition('type', 'award_nominee')
    ->condition('field_webform_submission_id.value', $webform_submission->id())
    ->execute();
  $nodes = Node::loadMultiple($entity_ids);
  foreach ($nodes as $node) {
    $node->delete();
  }
}

Although I think another webform handler could "handle" the deletions too.

The problem is the emails are being sent: one from the configured email handler, and one from the webform_submission->save() in the node creation handler. How can I prevent an email being sent from the node creation handler? $webform_submission->resave() seems to solve the problem like this.

$sid = '';
if ($webform_submission->id()) {
  $webform_submission->resave();
  $sid = $webform_submission->id();
}
