Makes edits, including adding, editing, resizing, moving and pasting (but not style changes).
Adds comments and replies to comments.
Joins a collaborative spreadsheet for the first time.
Manages the spreadsheet, like changing the password or restoring a spreadsheet.
You can also get notifications about different activities.
