Use an eyes reaction to start an access check
Mark a resource question with a reaction and have its current permission entries brought back for review.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
List Permissions
Tool to retrieve permissions for a specified resource. Use when you need to inspect who has access and what level for a given file or folder.
Why this helps
Important access questions can be buried in a busy thread and missed after someone acknowledges them.
- Turns a lightweight reaction into a concrete lookup.
- Keeps the signal attached to the message that names the resource.
- Makes access results available for a human decision.
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 check Files.com access when a Slack message receives the chosen reaction.
- 3Write one plain-language instruction to identify a named resource from the reacted message, list its permissions, and report the entries.
- 4Pick the reaction-added trigger and configure its available emoji or channel filter if appropriate; choose a report channel and test on a real message.
Questions about this workflow
Can the reaction change access?
No. The action only retrieves permission entries.
What should the message include?
Include a Files.com resource identifier so the lookup can target the right item.
