OnOff Shim / Custom LED during shutdown?

Hi there,

I recently bought an OfOff Shim and it works like a charm - thanks a lot.

However - I have a question:
I am using my RaspberryPi / OnOff Shim in a headless environment with a closed casket.
In order to notify the user, that the RPi is shutting down, I’d like to activate an LED until the RPi is finally shut down.

Can you give me any indication how I could achieve this?

Thank you and have a nice day,

Have a look see at this, might help.
