getPlayerInfoMap() in 1.17.1?

[Parent]

Hello, I'm once again stuck on the new version. With minimal documentation and support, I can't seem to figure out how I could getPlayerInfoMap() in the new 1.17.1 version of forge.

Here's where I want it (line 4):

@SubscribeEvent
    public static void onJoin(final LoggedInEvent event){
    	Entity player = event.getPlayer();
    	if(playerInfoMap().size() > 1) {
    		player.sendMessage(new TextComponent("Cannot be in multiplayer!"),event.getPlayer().getUUID());
    	}
    }

Any help would be appreciated.

The method is located in a public class called EventHandler, an Event Bus Subscriber.

and where is/was this method located?
and what does the "playerInfoMap" method do

Edit: try getOnlinePlayers since you use mojang mappings
