In the Druid conference submission portal, it is not possible to insert co-authors to the paper. An error notification appears making it impossible for me to add a co-author. I kindly ask you to add to the submission with the
number 70242 the following author: Liubov Pakhomova, University of Maastricht.
Thank you and kind regards,
