Set Minecraft multiverse-core chat?

I have a Minecraft server on which I have the plug-in multiverse core. If I'm in "Welt1" and write something in the chat then you can also read it in "Welt2". I would like to prevent that. I want every world to have its own chat. Is there a plugin that sets this or can I change it in the config? I'm at MC-Host24.com Thanks in advance. LG

I guess that's possible. Would go into the config of the plugin and look. If that doesn't work, I would simply search for a plugin on YouTube to prevent this.
