Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Signal Event
Tool to signal a specific event to be received by other processes or sessions. use when you need real-time coordination across browser sessions after verifying session is active.
Why this helps
A changed decision in Slack can leave other browser processes acting on an old coordination cue.
- Signal when a coordination marker is withdrawn.
- Keep connected browser processes aligned with a changed handoff.
- Reduce confusion caused by stale reaction-based cues.
Setup
Build it in a few focused steps.
- 1Connect Slack and Anchor browser to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to signal a named browser event when a designated reaction is removed from a Slack message.
- 3Describe the reaction and coordination event in one plain-language instruction.
- 4Pick the Message Reaction Removed trigger, use an optional channel or emoji filter, and choose a channel for run reports.
- 5Test by removing the designated reaction from a real coordination message.
Questions about this workflow
Does this stop or end a browser session?
No. It signals an event to other processes or sessions. Ending a session requires a different action.
Can this apply to any removed reaction?
Use the trigger's optional channel and emoji filters, and explain the intended coordination marker in the prompt.
