Action
Create Announcement

Why this helps
Teams may agree on wording in Slack but lose track of whether the update was actually shared with learners.
- Make the publish-ready signal visible in the original conversation.
- Reduce the need to remember a separate publishing step.
- Keep announcements tied to updates the team has reviewed.
Setup
Build it in a few focused steps.
- 1Connect Slack and Google Classroom to Notis once through the portal.
- 2Create an automation or ask Notis to publish a course announcement when a specified reaction is added to a ready-to-share Slack update.
- 3Pick the Slack reaction-added trigger and a channel for run reports, then test with one approved update.
Questions about this workflow
Does the reaction itself contain the announcement text?
No. The reaction identifies the Slack message; instruct Notis to use the associated update and course context.
Can this run for any emoji?
Specify the reaction and the kind of message it should approve in the plain-language instruction, then test it.
