Let say i have a task assigned to a group of people by using the "Start a task process", inside the user group have 3 people (e.g. User A, B, C), the task will be completed once one of the user approved or rejected from the user group.
Finally i need send an email to the initiator who approved or rejected the request from the user group. (User A or B or C)
How can i do it in o365 workflow? thanks.
