Pick Docs, Sheets and Slides from the Drive picker
The chat’s Drive picker now picks Google Docs, Google Sheets and Google Slides, with the Recent tab, file sizes, the icons as in Drive and the folder hierarchy with tabs.
A .docx can be converted and the copy used, and a listed native file connects without a check. It comes with what came before: Drive reads PDFs and converts Office files when connecting, and one picker replaces the two earlier ones (the whole Drive, a folder or a file).
