How to create pagination on CI4

This is how I do it for my Blog I'm building.

PHP Code:

// post model method

/**
 * getLivePosts ()
 * -------------------------------------------------------------------
 *
 */
public function getLivePosts() : PostModel
{
    $builder = $this->builder();

    $builder->where('status', 'published')
            ->orderBy('created_at', 'desc');
        
    // for method chaining
    return $this;
}

// Blog Controller

/**
 * -------------------------------------------------------------------
 * posts ()
 * -------------------------------------------------------------------
 *
 */
public function posts()
{
    $pager = Services::pager();

    $posts      = new PostModel($this->request);
    $categories = new CategoryModel();

    $data = [
        "featured"    => $posts->getFeaturedPost(),
        'posts'      => $posts->getLivePosts()->paginate(4, 'group1'),
        'pager'      => $posts->pager,
        'currentPage' => $posts->pager->getCurrentPage('group1'),
        'totalPages'  => $posts->pager->getPageCount('group1'),
        'categories'  => $categories->getTopCategories(),
        'title'      => 'Blog Home',
        'pageHeading' => 'Welcome to our Blog!',
        'subHeading'  => '',
        'typography'  => Services::typography(),
    ];

    echo view('Insitefx\Blog\Views\posts\index');
}

Notic the model returning $this for method chaining.
