Make a Slack reaction a simple event-search request
Mark a message with your chosen reaction and let Notis look for the described CoinMarketCal event.

Why this helps
Turning a promising Slack mention into research often relies on someone remembering to follow up later.
- Makes a reaction a low-effort handoff for event research.
- Keeps the original message as context for the lookup.
- Reports results where the team can review them.

- 1Connect Slack and CoinMarketCal to Notis once through the portal.
- 2Create an automation in the portal, or ask Notis conversationally.
- 3Give Notis one instruction to search CoinMarketCal for the event described in a message whenever a chosen reaction is added.
- 4Select the Slack message reaction added trigger, choose a run-report channel, and test by reacting to a real event mention.
