Why does Chronicle show a specific user performing actions instead of Chronicle itself?

When Chronicle performs certain actions in your workspace — such as archiving a channel — it sometimes needs to act with administrator privileges. It does this through the Slack API, acting on behalf of whichever admin most recently authorized the app. As a result, Slack shows that specific user as having performed the action, rather than showing Chronicle itself.

You can identify when Chronicle (rather than the user) performed an action, such as archiving a channel, by checking the message posted just beforehand — it details relevant information like the channel's last activity and members at the time.
