a. Go to WP Admin -> Plugins -> Editor -> WPLMS Customizer -> customizer_class.php
b. Locate the function _construct and add following code in it :

PHP Code:

  

add_action('wp_footer',array($this,'add_unit_auto_complete'));

  

c. Add following function in class:

PHP Code:

 

function add_unit_auto_complete(){
echo "<script>
jQuery(document).ready(function($){
$('#mark-complete').on('media_complete',function(){
$('#mark-complete').trigger('click');
});
});
</script>";
}

 

Note: You need to enable Unit Media lock for this and this would only work for self hosted videos.
