Email notification for approval

I wanna create an Email notification if a user started a task.
The email should be sent to a Group so they know, they have a new Task to approval.
once they approve or reject the form. The email should sent to user and group.

You can use 2 different Task Listeners, which would trigger as soon as the task begins to send an email and then after the task is completed can send an email to another group

Hi Niall,
