Will DFR0494 (UPS HAT for Raspberry Pi 4B) power on the Pi when power is restored?

There is conflicting and confusing answers to this question in other forums and discussions:

Will the DFR0494 (UPS HAT for Raspberry Pi 4B) power on the Pi automatically when power is restored in this scenario:

If the power goes out for a period of time longer than the batteries can maintain a supply to the Pi, and the device is then gracefully shutdown, will the DFR0494 power the Pi back on automatically once power is restored and the batteries have charged sufficiently?
