SEMICOLON notifications

Hi,

I would like the notification to be open for a few seconds and then close. This is not happening using the code below.
Please, can you help me?

<div id="custom-notification-message" data-notify-position="top-right" data-notify-type="info" data-notify-msg="<i class="icon-info-sign"></i> Welcome to Canvas Demo!"></div>
 
<script type="text/javascript">
    jQuery(window).load( function(){
        SEMICOLON.widget.notifications( jQuery('#custom-notification-message') );
    });
</script>
