Creating a simple chat/message board

Hello,

I’ve created a chatroom in my game and everything works properly when changing the multiplayer settings shown here.

I am now trying to find a way to have the chat work on an exported project. The end goal is to have multiple clients be able to type to eachother on their mobile devices. What the users say to eachother doesn’t need to be instantaneous by any means so if it worked more like a message board that would be good as well. What’s the next step I need to take to accomplish this task? Been stuck on this one for a while.
