Feature Request or Advice on Implementing - LED On When Another User Sends Audio

[ChZeman]

This is a GREAT project! I'm attempting to use talkiepi to control a remote radio transceiver. I can use the squelch output of the radio to send audio to the server, but I'd like to repurpose the Participants LED output to transmit the channel audio on the transceiver when another user is sending audio.

I also need this feature. Is there any progress regarding this issue? Seems some people might need it as well.
