How do you handle Project Tokens on Server?

Hello

I am looking to migrate a project which uses project tokens to manage logic of button states. I want to be able to have two control panels running the same project, however be able to read all the tokens from the server i.e. if I select a button on panel, the button on the second panel will also become selected. 

I have been reading the documentation and understand how drivers etc are centralised and controlled from the server, but how do I reference a token on a server i.e. I might have a button that when pressed, sends text to a text type token. I might want this to be read on another panel on a text item. How do I make this happen via server?
