Arghh. Deleted files. Need to restore!

Help please! 😕

In an overzealous clean out, I seem to have deleted an important file (s).

The result is I now see in Finder, under Devices 'calibre-1.6.0' as a drive. It appeared after the Trash emptying.

I've looked at other Forums online and they recommend restoring via iCloud.

Alot of guides recommend using the 'Restore files' option under 'Settings' in iCloud's web interface.

I don't see this on the interface. Hmm.

Instead, I only see:

- Reset Documents

- Restore Contacts

- Restore Calendars and Reminders

- Restore Bookmarks

Any suggestions?

I'm a little conscious that after 30 days these files will be irrevocably lost 😢

Thank you in advance!
