Create a PDF from a node after the node is deleted

I want to create a PDF from a node when the node is deleted.

I am rendering the node using the following code.

$entity = \Drupal::entityTypeManager();
$view_builder = $entity->getViewBuilder('node');
$build = $view_builder->view($node);
$output = \Drupal::service('renderer')->render($build);

The output comes from node.html.twig, whereas the actual template file should be node--content-type--full.html.twig.

I am using the Dompdf\Dompdf class to create and store the PDF file.

$options = new Options();
$options->setIsHtml5ParserEnabled(true);
$options->set('isRemoteEnabled', TRUE);
$dompdf = new Dompdf($options);
$dompdf->load_html($node_html);
$dompdf->set_paper('A4', 'portrait');
$dompdf->render();

How do I get the exact design of the node?
