Where do offline synced google docs get stored on Mac OS X?

If I turn on google docs/sheets/drive offline sync through chrome on os x and activate "Make Available Offline" for some doc, where is the doc stored locally on my machine? I am not talking about google back up and sync - I am talking specifically about activating offline docs sync through a browser (in this case chrome). This answer gives the answer for PC, Android, and Linux but not mac. I looked in all the typical Application Support folders as well as in Chrome Developer Tools --> Sources --> Filesystem and also Developer Tools --> Application --> IndexedDB but I cannot figure it out. IndexedDB --> GoogleDriveDs --> Offline shows an entry for offline synced files (and not others) but it doesn't help me find it locally on my disk. Thanks!
