Code

public function access(Route $route, RouteMatchInterface $route_match, AccountInterface $account) {

  /** @var \Drupal\group\Entity\GroupInterface $group */
  $group = $route_match
    ->getParameter('group');

  // This tab should not show up unless there's a reason to show it.
  if (!$this->moderationInfo
    ->hasPendingRevision($group)) {
    return AccessResult::forbidden('No pending revision for this group.')
      ->addCacheableDependency($group);
  }

  // Unlike Drupal core, we allow revision viewing if you have 'view' access
  // to the group along with the 'view latest group version' group permission.
  // This allows access modules to have more say over who can view revisions,
  // rather than having to swap out this class to add permissions.
  //
  // See core issue: https://www.drupal.org/project/drupal/issues/2943471.
