How to synchronize ui in unity unet?

Question

Unity

I'm trying to make a rock-paper-scissors game on Unity in multiplayer. Made the mechanics of the game. I'm trying to add multiplayer using UNET. But in the end it turns out that in 2 clients the selection buttons and the text are not synchronized (watch the video). How to make the text change in both clients when the first player is selected?
