Jetpack Publicize

I”m feeling frustrated. I’m trying to use Jetpack to publicize a custom post type from the Event Manager plug-in. I’ve found this article: https://wordpress.org/support/topic/jetpack-publicize-custom-post-types-events-manager

I’ve read through it, and set up the mu-plugins folder correctly, went to: http://pastebin.com/Th6GRpZk and copied the RAW Paste Data into a .php file, I revised the supports array to read: $supports = array(‘custom-fields’,’title’,’editor’,’excerpt’,’comments’,’thumbnail’,’author’,’publicize’,’revisions’);
so that it includes the publicize function, uploaded that to my mu-plugins folder, but I’m still not seeing the publicize function on the custom post type.

I’m not savvy with WP code so I’m not certain if I’m doing this correctly.

My entire file looks like:

<? php
/*
 * This snippet will add support to post revisions at event CPT
 */
function em_mod_support($supports){
	$supports = array('custom-fields','title','editor','excerpt','comments','thumbnail','author','publicize','revisions');
	return $supports;
}
add_filter('em_cp_event_supports','em_mod_support',1,1);

?>

Can someone help me figure this out?

Thanks
Pattie
