How to show who added to list using Pun2

Options

In short - I've got issue when I trying to added to a list players who clicked the button and see who joined.

Basically I got Patient script who can by trigger see what player is next to it and added to certain list - witch works. The same I'm trying to do if the player go near that patient and click "Join". I can only see in the editor the unity client. if the other clients trying to join it seem to working but only on their clients because the list that hold the players who clicked the join button didnt change and I can see only mine. What am I doing wrong?

here the visual of seeing that I can see both players near to it. but the "Treating users(who clicked join

Patient have photonview and instantiate through the network

This Function that add to that list when clicked

OnJoinPatient is the button action

Player data that in the same component as the player
