iPhone/iPad backup folder empty when viewing on Mac, devices say they are backed up

I am trying to restore some Notability files from a backup on my iPad Pro, which I accidentally deleted. In the iPad settings under iCloud>iPad name, the device says it was backed up to iCloud lastnight. However, when I plug the iPad into my Macbook via USB and look in Finder, there are no backups shown.

I have tried viewing the backup folder directly via Finder>Go>Go to folder, this file path: ~/Library/Application Support/MobileSync/Backup/

The folder is empty, despite the iPad saying it was backed up. I also tested this with my iPhone 17 Pro with the same result. Could this be an issue with the MacBook? I have attached images below of the Finder iPad window and the empty backup folder.
