Cubase 12 Thumbnails

I’ve recently had to do a clean install of Windows 10 Pro on one of my PCs. As far as Cubase 12 is concerned OneDrive had backed up all my Cubase Instuments and FX (the thumbnails) - how do I restore these back again? Is there a OneDrive setting I need to enable as it is a massive timesaver.

Thanks in advance

TBH, OneDrive is not a real backup.
