At some point in the winter of '21 I created a folder of bookmarks that was saved in the 'bookmarks menu'. At a later date, hard to say when but probably '22 or early '23 I deleted these bookmarks. I now desperately need to recover them. The oldest auto-backup from 'Manage Bookmarks' -> 'Import and Backup' -> Restore is dated mid '23 and does not contain the deleted bookmarks. Is there any hope of recovering them? For example via the Recycle Bin or by using a data recovery tool? Or will they have been overwritten?
