Version 2.

Create your first menu

public class MySimpleMenu extends FurnaceMenu {
    public MySimpleMenu(JavaPlugin plugin) {
        super(plugin, "My Menu Title");
    }
    
    @Override
    protected void onCloseMenu(Player player) {
        //event when user open your menu
    }
    
    @Override
    protected void onOpenMenu(Player player) {
        //event when user close your menu
    }
}

Now you have your menu, let's add it to menu system.

public MyPlugin extends JavaPlugin {
    GuiManager guiManager;
    
    public MyPlugin() {
    
    }
    
    private void initMyMenus() {
        MySimpleMenu simpleMenu = new MySimpleMenu(this);
        guiManager.registerMenus(simpleMenu, "MySimpleMenu");
    }
}

To init GuiManager, please refer to this documentation :

        addItem(item, FurnacePlace.SMELTING);
    }
    
    @Override
    protected void onOpenMenu(Player player) {
