When upload files using the timeline, it gets uploaded to the notes entity. While timeline displays them in chronological order, it gets messy in the timeline as timeline can also displays various other information. Now, it is possible to show a subgrid for notes entity. however, it is not possible to download the file from the grid as the link is not displayed. If this grid can show the link for downloading the file, it gives the same experience as the grid for sharepoint docs.
