Slack Actionable Message with Multiple Buttons

[Ben_Young]

I am looking to get the user ID from the person who interacted with a Slack Actionable Message. From the Automation Run History, I see the User ID is saved, but for an audit trail I would like to automatically assign that user to the record they acted on.

I have the same request.  I want to update a field with the user who took action.  There is an option under fields to select "User who took action", and either ID, Email, Name or Profile picture is available.  My problem is it does not appear to work.
