Multiplayer - How to push messages to clients?

Hi,

I’m trying to open a loading screen when the server launches a new map (with server command travel server), however I’m having difficulty getting the screen to load on the clients, as I don’t know how to access them.

It seems like a really basic thing as I’ve got the whole game working in multiplayer apart from this, but what am I missing? Is there a way for the server to push a command to all of the clients?

Any help is massively appreciated.

Cheers,

Steve
