How to create different voip channels for different teams?

I got my voice chat working following Positional Voice Chat in Unreal Engine 4 || 6 Minutes Series - YouTube. Now i want to make different voice chats for different teams, so they cant hear each other. Could not find anything about it. I tried using Mute Remote Talker, but this node does not work or i used it in a wrong way, anyways, i neither find something about it.
