Why this helps

- Make an approval decision easier to notice in its conversation.
- Use the existing Slack message instead of creating another update.
- Choose the reaction based on the submitted decision.

- 3In one instruction, ask Notis to add the supplied emoji reaction to the supplied Slack message after an approval update.
