Need modal dialog Confirmation prior to submit Flow Action
We have requirement that when user click "Submit" button in Flow Action, a Confirmation modal dialog must be presented, there are 2 buttons, "Confirm" and "Cancel". If user clicked "Confirm", it will submit assignment, workflow moved to next step; if user clicked "Cancel", modal dialog closed and flow nothing happened.
The Modal Dialog must be a Local Action, because we have to put some instructional message on that dialog. Please help to provide solution.
