Changing teams and player Id?

I am still learning blueprint scripting and have followed one of the Unreal tutorials on setting up a Steam multiplayer game (Blueprint Multiplayer: Project Overview | 01 | v4.11 Tutorial Series | Unreal Engine - YouTube) . I am trying to implement teams into the project but I have been stuck on this for days now. It is set up so all of my player info is stored in a structure i.e player name, player image etc. I was thinking maybe I should add the player Id and Team Id to this struct? I have created an extra window in my lobby UI. The closest I came was to being able to switch teams but it not replicating properly. Is there anybody who may be able to try and explain a method of how to do this or even post any BP pictures?
