"Layout Options" Missing from custom post type

ok, so the old way of editing the “meta” settings on the templatebuilder config is no longer valid?

Ok, I have multiple post types, but the example is not clear as to how to add more than one. I am getting an error when trying to update it. I think the issue is with the comma separator.

function add_builder_to_posttype($metabox)
{
	foreach($metabox as &$meta)
	{
		if($meta['id'] == 'avia_builder' || $meta['id'] == 'layout')
		{
			$meta['page'][] = 'event' ,'bar' ,'restaurants', 'saunas'; /*instead add the name of the custom post type here*/
		}
	}
	

	return $metabox;
}
