Wordpress: How to paginate a list generated by PHP?

I'm using a plug-in called WP Calendar to display a list of events. It's a plugin that I activated in my WordPress admin, and then I added the PHP code below to my template file. Currently, the plug-in is set to display 20 events, however, I need to display 100+ events so I would like to paginate this list. Does anyone here have any pointers or links to tutorials on how to do this? Thank you!

<?php fse_print_events_list(
  array( 'number'   => 20,
         'before'   => '<div class="calendar">',
         'after'    => '</div>',
         'template' => '<h1>{event_startdate}</h1><h3>{event_subject}</h3><p>{event_description}</p><br />'
  )
); 
 
?>
