I’m not sure how to do that.
However, I did try a couple of other things. Each time I got a Catchable Fatal Error for turning it into a string.
For example, when I tried to create a shortcode for it, I got:
Catchable fatal error: Object of class Anthologize could not be converted to string in /home/server/mydomain.com/wp-includes/shortcodes.php on line 287
