Can’t find external SQLite db

I’m running the latest docker image (community edition) and have mounted an external SQLite db file under /usr/app/data but when I go to add a new base, it doesn’t seem to be picked up and I can’t see SQLite as a source.

I know thing have changed for SQLite setup since I last tried this but I can’t figure this out. Am I missing something obvious?

Thanks for any help.
