I have below plugin code that displays custom post types as a recent post widget. I would like this code to also display the summary excerpt of the posts and the featured image of the posts as well. What and where should i add to call featured image and the excerpt text?

I would be glad if you can help.

        <?php
    }
}

The main tricks is here at this part-

<li>
    <?php has_post_thumbnail() ? the_post_thumbnail() : ''?>
    <a href="<?php the_permalink() ?>"><?php get_the_title() ? the_title() : the_ID(); ?></a>
    <?php if ( $show_date ) : ?>
        <span class="post-date"><?php echo get_the_date(); ?></span>
    <?php endif; ?>
</li>
