Add links to the step indicator

I agree, this would be an awesome feature. I tried to make the examples work in the current release, and failed with both of them ... so an update and a working example would be fantastic :)

any update please?

Hello folks.
I created an issue to make it easy to extend the MultistepController for another reason. https://www.drupal.org/project/simple_multistep/issues/3501547 ✨ Make MultistepController easy overrided Active
but I also had to implement the navigation between the steps.
So, this is how I did.
Apply my patch in the issue above.
Extends the MultistepController creating your custom controller.
Inside this class override the addStepIndicator.
In my case I created another Step indicator extending from StepIndicator and this is the result.

/**
 * The ResourceStepIndicator class.
 *
 * @package Drupal\uwas_resource\SimpleMultistep
 */
class ResourceStepIndicator extends StepIndicator {

  /**
   * Render the step indicator.
   *
   * @param array $form
   *   The form array.
   */
  public function render(array &$form): void {
    $form['steps_label'] = $this->createStepsIndicator();
  }

  /**
   * Create steps indicator.
   *
   * @return array
   *   Returns the steps label.
   */
  public function createStepsIndicator(): array {
    $data = [
      '#type' => 'container',
      '#weight' => -100,
    ];
    foreach ($this->getSteps() as $step_number => $step) {
      $format_settings = $step->format_settings;
      if ($format_settings['show_step_title']) {
        $button = [
          '#type' => 'button',
          '#value' => $step->label,
          '#validate' => [self::class . '::moveStep'],
          '#step_number' => $step_number,
        ];
        if ($this->currentStep === $step_number) {
          $button['#disabled'] = TRUE;
          $button['#attributes']['class'][] = 'active';
        }
        $data[] = $button;
      }
    }
    return $data;
  }

  /**
   * Move step.
   *
   * @param array $form
   *   Form array.
   * @param \Drupal\Core\Form\FormStateInterface $form_state
   *   Form state object.
   */
  public static function moveStep($form, FormStateInterface $form_state): void {
    $multiStep = $form_state->get('multistep_controller');
    $triggering_element = $form_state->getTriggeringElement();
    $step_number = $triggering_element['#step_number'] ?? -1;

    $entity_form = $form_state->getFormObject();
    if ($entity_form instanceof EntityFormInterface) {
      $entity_updated = $entity_form->buildEntity($form, $form_state);
      $entity_form->setEntity($entity_updated);
    }

    $form_state->set('step', $step_number);
    $multiStep->updateCurrentStep($step_number);
    $form_state->set('multistep_controller', $multiStep);
    $form_state->setRebuild();
  }

}
