A family of Microsoft word processing software products for creating web, email, and print documents.
The bot is giving you a Windows answer to a Mac question. On a Mac, there are 2 lists of recent files, one for files stored locally and another for online documents. These are stored in .plist files in your hidden user Library folder. I used to track the names and locations of these files, but Microsoft is constantly changing them and I finally gave up the effort.
While the approach is similar to using a cannon to kill a mosquito, the best workaround I can think of is to uninstall Office following these steps: Uninstall Office for Mac. Then reinstall from the Subscriptions page of your Microsoft account.
