[urgent] Is it possible to display a different page to different users?

We’re developing an app where there are 2 players playing against each other.

They each have to pick in turns based on what turn it is.

Now, here’s the question:

Is it possible to display a screen to 1 connected user and not to another connected user?

Cause I don’t want to show the “picking” screen to the player that is not currently picking.
