How to make a messaging plugin?

Hey, so I'm trying to make a plugin that sends the player a message when they go in a certain world.

Currently, this code does absolutely nothing, any idea why? I'm sorta new to this.

Code:java

public class Main extends JavaPlugin implements Listener{
 
    @Override
    public void onDisable() {
 
    }
 
    @Override
    public void onEnable() {
        Bukkit.getPluginManager().registerEvents(this,this);
    }
 
    public void onWorldChange(PlayerChangedWorldEvent event){
 
        String world = event.getPlayer().getWorld().getName();
        Player p = event.getPlayer();
 
        if (world.equalsIgnoreCase("pvp")) {
            p.sendMessage("###########################");
            p.sendMessage("Type /kits to start off!");
        }   
    }
}
