Display ‘roles’ after title

Hey guys!

I would like to display the user’s role after the title and tried after_title=”{al:roles}” but that doesn’t work. Is there any way to display the user’s role?

The complete shortlink I use:

[authors_list after_title="{al:roles}" style="1" columns="3" show_count="no" orderby="display_name" skip_empty="no" roles="kulturschaffende,locations" show_bio="no" bio_word_trim="25" show_link="no"]

Thanks,
Nico
