If you wish to collaborate on a sheet and save any messages sent to other users, comments should be used. You can add a comment to any part of a sheet, and other colleagues working on the sheet can add replies. Once the comment has been actioned, it can be marked as resolved.

To edit a comment, click on the cell that contains the comment, then click on the Ellipses in the comment box. Choose Edit.
