How to hide players microphone down indicator

I cant figure out how to hide the little microphone icon above players heads while using microphone, searched around gmod wiki a ton, anything anyone here knows?

If you want to solve it with lua, Kogitsune did already an good script for it.

Thanks, would be nice to have a took to toggle it per player with ease, but that will probally do nicely. :smiley:
