hook_help function missing in .module file

Hi create MR for this issue.
Please review.
Thanks

I will review this MR.

MR !12 looks good to me. So moving it to RTBC.

Thanks.

This is great, however where's the link to the config page?

This is how the webform module does it:

/**
 * Implements hook_help().
 */
function webform_help($route_name, RouteMatchInterface $route_match) {
  if (!$route_match->getRouteObject()) {
    return NULL;
  }

  // Get path from route match.
  $path = preg_replace('/^' . preg_quote(base_path(), '/') . '/', '/', Url::fromRouteMatch($route_match)->setAbsolute(FALSE)->toString());
  if (!in_array($route_name, ['system.modules_list', 'update.status']) && strpos($route_name, 'webform') === FALSE && strpos($path, '/webform') === FALSE) {
    return NULL;
  }

  /** @var \Drupal\webform\WebformHelpManagerInterface $help_manager */
  $help_manager = \Drupal::service('webform.help_manager');
  if ($route_name === 'help.page.webform') {
    $build = $help_manager->buildIndex();
  }
  else {
    $build = $help_manager->buildHelp($route_name, $route_match);
  }

  if ($build) {
    $renderer = \Drupal::service('renderer');
    $config = \Drupal::config('webform.settings');
    $renderer->addCacheableDependency($build, $config);
    return $build;
  }
  else {
    return NULL;
  }
}
