Why this helps
A withdrawn reaction can signal a changed assumption, but the reason and related event may be easy to lose in a busy channel.
- Treat a removed confirmation as a cue to review.
- Bring possible event matches into the run report.
- Help prevent stale assumptions from carrying forward.
Setup
Build it in a few focused steps.
- 1Connect Slack and Evenium to Notis once in the portal.
- 2Create an automation or ask Notis to retrieve Evenium events when a planning message loses its checkmark reaction.
- 3Select the Message Reaction Removed trigger and filter for the checkmark emoji if available.
- 4Choose a run-report channel and test by removing a checkmark from a real planning message.
Questions about this workflow
Does it detect why the reaction was removed?
No. It detects removal and retrieves events; the reason needs human context.
Does it restore the confirmation?
