PHP code to filter by ‘owner’

Hi, thanks for this plugin. I’m trying to do something rather simple but my PHP knowledge is limited, and I can’t seem to get it to work. I want to embed the following code on a custom WP page template which would display a list of events created by the event owner- which is the same as page’s author:

           <?php
            $authorusername = get_the_author_meta('user_nicename');
            
            echo EM_Events::output(array(
                        'owner'=> $authorusername,
                        'limit'=>10, 
                        'pagination'=>1)); 
            ?>
