Get player name in multiplayer

That’s the problem, I can’t do it because I’m dumb

I think it goes something like this: The player enters the server >>> Cast to some blueprint on the map >>> The BP level takes the names of the players in the previous BP >>> It sends the player name to the widget. However, I still don’t understand how the server will transmit to the right player, it still confuses me a lot.

I’m still going to create a color system for each player and I can’t even imagine the pain it will be
