Why this helps
People can lose track of existing access while coordinating a share in a busy conversation.
- Makes existing access visible during a sharing discussion.
- Supports a human check before proceeding.
- Keeps the resource context attached to the request.
Setup
Build it in a few focused steps.
- 1Connect Slack and Files.com to Notis once through the portal.
- 2Create the automation in the portal or ask Notis to retrieve Files.com permissions when a sharing message gets the chosen reaction.
- 3Write one plain-language instruction to identify the resource, list its current permissions, and report them for review without modifying access.
- 4Choose the reaction-added trigger, select an appropriate available emoji or channel filter, choose a run-report channel, and test on a real share discussion.
