Clear recents list in Microsoft Office for MAC. Word Excel Powerpoint

Microsoft Office for MAC 2019 uses recents in Word, Excel and PowerPoint.  There is no option in the MAC version to clear out the whole list and users need to remove the recents one by one using "remove from recents".  Alternatively the following bookmark files can be deleted or renamed:

~/Library/Containers/com.microsoft.Word/Data/Library/Preferences/com.microsoft.Word.securebookmarks.plist

~/Library/Containers/com.microsoft.Excel/Data/Library/Preferences/com.microsoft.Excel.securebookmarks.plist

~/Library/Containers/com.microsoft.Powerpoint/Data/Library/Preferences/com.microsoft.Powerpoint.securebookmarks.plist
