Allow editing tags without write permission?

Hi,
I’m using Nextcloud 28 with Memories and Recognize apps. I have one directory specific for Memories which has access rights of 555, i.e. I don’t want anyone to change or delete files. However, I would like to be able to edit the tags that recognize gave the images. Is this possible somehow?

As I understand, tags are not written to the files, but to a separate db, so in theory this should be possible. However, when I select images and click on “Edit Metadata” I get a permission error.
