Public Shares of Group Folder should not be tied to user account

We use Group Folders tied to project groups from our LDAP and this works well. However, I have a requirement for a public share of a group folder.

It seems that while the folder itself is not tied to a particular user, the share itself is - you can see here that the folder is “shared by Dave Page”. If my access to that group folder is removed, the share link stops working.

Is there a way to create a share link which isn’t tied to a user? I’ve looked through the admin settings and not found anything.

We’re running Group Folders 6.0.5 on Nextcloud 18.0.3 via Docker.
