Show the “Last published lessons” in frontEnd

Hello,
I am a happy customer of the Theme EDUMA. And I have the following question:
You are designing a theme and I want to show the “last created lessons” with their respective permalink, but I don’t get it with a WP query. I have something like this:

   <?php
$args = array('
orderby'=> 'id',
'order' => 'DESC',
'post_type' => 'lp_lesson',
'posts_per_page' => 5,
'post_status' => 'publish'
);
$q = new WP_Query($args);

while ( $q->have_posts() ) : $q->the_post();

?>

    <li>
        <a href="<?php the_permalink(); ?>">
          <?php the_title(); ?>     
        </a>

    </li>
    <?php
endwhile;
wp_reset_query();

But I don’t get the permalink for every lesson.
