drupal_set_message deprecated in drupal 9

Create a function:

//---------------------------------------------------------
function drupal_set_message($message = NULL)
    {
    $messenger = \Drupal::messenger();
    if (isset($message)){
      $messenger->addMessage($message,'status',FALSE);    }
    }
//---------------------------------------------------------

Replace

 drupal_set_message(array(
        '#type' => 'markup',
        '#markup' => $tle));
