Sharing/Showing a Canvas UI Object to Another Player


Does anyone know how to share a canvas ui object with another player?

Currently, i have a World Space canvas object that i want to show/share with another player.

Imagine, that a player(named Davinci) have an iPad or smartphone.
This smartphone is a world space canvas ui.
Davinci wants to show what he is doing in his smartphone with another player.

How do i achieve this.?
