Create or provide access to users locations, based on the server, returning the train number, and position (like in the dispatcher screen) for everyone be able to create integrations.
My integration proposal:
Discord Bot and Discord Server integration:
When user joined a session, join a discord server with this bot and save his currently UserID on game
The bot will be able to move this person to the correct VC to communicate with Dispatchers since the game does not have a radio communication with only the desired dispatcher.
Integration will be able to tell where the user is to correctly change the user VC when needed, others trains in the current station will be able to communicate between each other and with the dispatcher.
