Toasts or Bootboxes, is this possible?

Part 1: I have a ServerConnect that refreshes on a short interval. I’d like to display a Toast (preferably) or even a Bootbox when the data changes or has a new record added. Is this possible with the new Flows stuff?

Part 2: If this is possible is it possible to reuse the flow on all pages or as an include so that no matter what page is being viewed the Toast will pop up?
