Adding buttons to main menu 1.16.5

[TheKralGame]

hello i want to add a button to main menu.

Screen myevent = event.getGui();
if (myevent instanceof MainMenuScreen){
	myevent.addButton(new Button(20, 20, 20, 20, new StringTextComponent("Text"), (e)->{

		System.out.println("Sa");
				
	}));
}

It says addButton is protected. I tried accesstransformers thing.

and i wrote this

protected net.minecraft.client.gui.screen.Screen addButton(Lnet/minecraft/client/gui/IGuiEventListener;)Lnet/minecraft/client/gui/IGuiEventListener;
protected net.minecraft.client.gui.screen.Screen addListener(Lnet/minecraft/client/gui/IGuiEventListener;)Lnet/minecraft/client/gui/IGuiEventListener;

 

but it is not working.

 

The code of addButton and addListener

protected <T extends Widget> T addButton(T button) {
    this.buttons.add(button);
	return this.addListener(button);
}

protected <T extends IGuiEventListener> T addListener(T listener) {
	this.children.add(listener);
    return listener;
}

 

Please help me
