On the Portal Screen on Dynamics 365, want to be able to use the edit and delete buttons without the user logging in.

Currently, users who have access to the portal site, but can add (upload) attachments, once uploaded files, edit and delete must log in to the system.
Therefore, if they just use the portal site, or use Cokkie, monitor the web session, without logging in, edit the file that the user uploaded freely, and, they wants to be able to delete.
