Script to download Google Drive documents as RTF

I have a collection of documents that were written collaboratively on Google Drive, that I need to download into my DevonThink database so they’re searchable and locally backed up. (See attached.)

I can open each one individually in Google Drive and navigate to File > Download as > RTF, but there must be a way to automate this. :unamused: Right?

Over here I go to the Drive interface in a browser (here, Safari), make a selection of numerous files, right click the seletion, and choose “Download” from the contextual menu. Drive converts the documents that need conversion, then downloads them all in a .zip file. I don’t think you can do this in Finder; so I’m thinking a script might not be feasible. Be happy to be wrong, though :confused:
