That wouldn't work for me as I try to avoid flatpak wherever possible. However, murena.io where I host my unofficial manuals uses Only Office to view the files I created in SoftMaker (17] and LibreOffice (15). I loved using Okular pdf viewer to extract text, tables and images into Text Maker. Once you make the font you choose as default for the document in Text Maker, text extracted is turned into Font and size of font you made default. Tables from Okular drom to basic roman but not a big isdue; just highlight all the cells, press Ctrl+ Space and the font changes to what you made default in the document. Also their Ribbon is better thought out than MS, and if you prefer the same menu bar as Word 2003 equivalent you can change that. Oh, and you know in Word you can only cut tables? In TextMaker you can delete them!
