How to list all users of posted in wordpress

$args  = array(
'orderby' => 'display_name'
);
$wp_user_query = new WP_User_Query($args);
$authors = $wp_user_query->get_results();
if (!empty($authors))
{
    echo '<ul>';
    foreach ($authors as $author)
    {
        $author_info = get_userdata($author->ID);
        echo '<li>'.$author->ID.' '.$author_info->first_name.' '.$author_info->last_name.'</li>';
    }
    echo '</ul>';
} else {
    echo 'No authors found';
}

I'm using post filter by post author. Above code displays all the users so need to display only authors who posted in the blog.

just like wp_list_authors() function but i need to get the author id intead of author name. because I need to create a dropdown list. While someone change the option, then I need to get the post by that author in AJAX

Update 1:

Hope this help:

$posted = get_posts([
    'post_type' => 'your_custom_post_type',
]);
$author_ids = [];
foreach ($posted as $post) {
    $author_ids[] = $post->post_author;
}
$author_ids = array_unique($author_ids);
if (!empty($author_ids) )
{
    echo '<ul>';
    foreach ($author_ids as $user_id)
    {
        $author_info = get_userdata($user_id);
        echo '<li>'.$user_id.' '.$author_info->first_name.' '.$author_info->last_name.'</li>';
    }
    echo '</ul>';
} else {
    echo 'No authors found';
}

Make sure to change post_type to your post type and each user has both first_name and last_name.

There's a missing argument on Codex reference: has_published_posts.

$args = [
  'orderby' => 'display_name',
  'has_published_posts' => true
];
$authors = new WP_User_Query($args);
...

It's better to look for inside class file because info on Codex is not always up-to-date.
