Nie działająca funkcja

Hejka, chciałem napisać formatowanie czatu ;ppp i coś nie działa

Wersja to 1.16.4

To kod z klasy Main:

package com.poyebany.main;

import org.bukkit.command.CommandExecutor;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.AsyncPlayerChatEvent;
import org.bukkit.plugin.java.JavaPlugin;
import com.poyebany.commands.*;
import com.poyebany.managery.*;

public class Main extends JavaPlugin implements Listener {
    private static Main instance;
    @Override
    public void onEnable() {
        instance = this;
        saveDefaultConfig();
        System.out.println("[Core] Dostepne Procesory: " + Runtime.getRuntime().availableProcessors());
        System.out.println("[Core] Aktywne Watki: " + Thread.activeCount());
        getServer().getPluginManager().registerEvents(this, this);
        getCommand("gamemode").setExecutor((CommandExecutor)new Gamemode());
        getCommand("broadcast").setExecutor((CommandExecutor)new Broadcast());
    }

    public static Main getInst() {
        return instance;
    }

    @EventHandler
    public void onChat(AsyncPlayerChatEvent event) {
        ChatManager chat = new ChatManager();
    }

    @Override
    public void onDisable() {
        System.out.println("[Core] Plugin zostal wylaczony");
    }
}

To kod z klasy ChatManager (dziala):

package com.poyebany.managery;

import com.poyebany.main.Main;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.AsyncPlayerChatEvent;

public class ChatManager {
    @EventHandler
    public void onChat(AsyncPlayerChatEvent event) {
        Player p = event.getPlayer();
        event.setFormat("x" + "%s");
    }
}
