Implementation Steps:

6. Now Navigate below Steps
7. Enter the Name and Label
Based on the Attached Imaged I have used my END Date and TIMER STATUS
if Status = Pending (TIMER SHOULD BE : Paused)
if Status = In-Progress (TIMER SHOULD BE : Warning)
if Status = Completed (TIMER SHOULD BE : Success)
That's it 🙂
