And it is not possible to integrate it through ts3, for example, pay our server and use it as a medium, I think that in minecraft through java, they have implemented a chat approach, when it was not possible to perform this action, I know it has nothing to do, but it is java and there are always relationships, the problem is how to implement it.
we should look for some API that is compatible with lucera, then replace the msg by some kind of menu, which allows you to mute your microphone, turn it on and / or get the voice chat server, to fight or talk to other players.
the second, is how to relate this, by means of a server configuration, that is to say, to put the port of your ts3 server or data of your discord server, the second option was used in the minecraft api, by means of those data they could give light to the voice chat.
