Choose a preset duration for vibrate sound profile (or cancel the preset menu to set a custom duration).
After confirming duration, vibrate mode is set for that duration. Flow then vibrates to notify time elapsed and sets original sound setting after duration elapsed.
Exit without activating timer by choosing "Cancel" in Custom Duration dialog or "Back" button in Choose End Time dialog.
V2: Added early cancel button to the flow's persistent notification.
V3: Added active remaining time display (Countdown) to notification, replacing the existing static chosen duration text. [Credit to Finch Nelson's brilliant Countdown Timer flow.]
V4: Added setting a custom duration by choosing an end time. [Credit to Thor Snekkestad's brilliant Timer flow.]
Currently at 21 blocks total and should be my last version (unless something fails catastrophically).
Your opinion of this flow, should you decide to share it, would be greatly appreciated.
