How to give an alert when other users sessions are logged out

Hello, I have added the workflow step “Log out other users session” when a user logs in on another device.

(Thanks to @fayewatson for showing how to do this here):

How can I then get an alert to show up on all other devices that are logged out? Say an alert that states “You have been logged out as you have logged in on another device”?

Hi, Did you happen to find a solution for this at all?

I’ve tried a couple of ways such as setting flags in elements then showing popup depending on flag value & also played around with the ‘user is logged out’ workflow but I think the issue is the workflows wont run ‘because’ the user is now logged out.
