Hide Point Awards in Activity Stream

I’m trying to hide the user’s point awards in the buddypress activity stream. I found this code:

function bp_activity_do_not_save( $activity_object ) {
	
	$exclude = array(
	        'updated_profile',
	        'new_member',
	        'new_avatar',
	        'friendship_created',
	        'joined_group'
	    );
	
	if( in_array( $activity_object->type, $exclude ) ) {
		$activity_object->type = false;
	}
}
add_action('bp_activity_before_save', 'bp_activity_do_not_save', 10, 1 );

I can’t figure out what slugs I need to add to the $exclude_array to prevent the points update. Thanks.
