It would be great to have a slider to lower non-teammates when they are talking.

It gets really annoying when you're trying to chat in teams and there are people talking in the main chat at the same time. Muting them outright would be a problem because you need to hear them sometimes. But if there was a way to reduce their volume when someone in your team is talking it would be very useful.

I'm imagining a slider in the audio options which would control how much their voice volume would be lowered, ranging from not lowered at all to completely muted.
