- Keep document follow-up visible
- Reduce accidental work loss

- 3Tell Notis to list relevant Draftable comparisons and report items needing a new owner or confirmation.
- 4Pick Message Reaction Removed as the trigger and choose where reports go.
- 5Test with one real reaction removal tied to a document discussion.
Questions about this workflow
Can it know why the reaction was removed?
