Edge on Linux and Office document preview

Currently I have switched over to Edge as the primary browser on both Windows 10 and Linux (Ubuntu) systems. While on Windows 10, the Edge browser seems to support preview of Office docs without downloading them (s.a. when using Office Outlook, I can click on the Word or Excel or Powerpoint attachments and view them in browser, nearly perfectly), I cannot do the same in Edge browser on Linux. Wondering if there are any plans afoot to bring this capability also to Edge browser on Linux ? If so, by when ?
