Cubase media browser - any OneDrive users - how to make it show up in the folder browser list?

Strangely Cubase does not recognise the OneDrive folder I have sitting on my Mac, synced via the OneDrive client app.

It is visible in Finder, but I can’t seem to rescan the ‘This Computer’ parent folder, only its sub-folders. I suspect if I could rescan it, it may show up. Any ideas?
