- 3Choose Message Reaction Added and a channel for run reports.
- 4Test by reacting to a real message with confirmed attendees and timing.
Questions about this workflow
Can a reaction signal readiness when details are absent?
No. Have Notis check the message context and request clarification if essential scheduling details are missing.
Can the same reaction be used for another purpose?
For predictable runs, reserve the chosen reaction for this scheduling handoff in the relevant channel.
