Support more file formats
Currently only common formats like xls, doc, ppt etc. are supported. It would be good if other file formats could be made readable: Adobe Acrobat and also Adobe Cloud (PS, Ind, XD etc.)
Sharing the screen is the work around showing different formats however, file formats that should be supported in my opinion include all the Microsoft products such as word, excel as well as Adobe files. It would make life some much easier as well as increase your business profile as more people will want to utilize Microsoft teams.
