How to add pagination to programmatically rendered search result template

Question

I am trying to implement the pagination in drupal 8 custom page.

I have a custom array which I am rendering using theme, I need to add pagination for it.

    $internal_result = array_merge($internal_result, $basic_data);
    $response = new AjaxResponse();
    $terms['internal'] = $internal_result;
    $renderable = array(
        '#theme' => 'search_result_template',
        '#data' => $terms
    );
    $rendered = \Drupal::service('renderer')->render($renderable);

I need to add pagination for above result. Can anyone help me?

I tried with the search_result template and it worked, hope this helps you :

$output['prefix']['#markup'] = '<h2>Test page</h2>';
//This sets up necessary global variables for the type => #pager
$page = pager_default_initialize(5, 2);
$render = [];
  $output[] = [
    '#theme' => 'search_result',
    '#result' => 's',
  ];
$pager = [
  '#type' => 'pager',
];
$output['suffix']['#markup'] = '</ol>' . \Drupal::service('renderer')->render($pager);
return $output;

We just need to set up the global variables which help to process rendered array to output pagers items. And add a pager to the suffix.
