BuddyPress.org

I have the following code in my functions.php file

add_filter( 'bp_after_has_activities_parse_args', function( $retval ) {
   $retval['action'] = array(
        'activity_update',
        'activity_comment',
		'friendship_created',
		'rtmedia_update',
		'new_member',
		'created_group',
		'joined_group',
    );
    return $retval;
} );

It works great… BUT when I try to filter the buddypress stream everything appears. There is no filtering ability. Is this the right function to use?
