When trying to mention a user on slack, We have an action to post a message. Using that action if we send "@xyz" that is posted as a plain text but it is not mentioned on slack.
Did anyone implement the same? If yes kindly advice.
I did find a solution to this: As referenced below by @rad2 - "userID" is different than their display name or username in Slack. If you open a user's profile by clicking their name, hit the Three Dots under their profile and select "Copy Member ID" - that's the ID you'll need to ref. in the flow to properly tag someone.
