    }

    @Override

        if(isMouseOver(mouseX,mouseY)){

            ClientNetworking.sendItemClickPacket(stack);
            if(!MinecraftClient.getInstance().player.getInventory().insertStack(stack)){
                MinecraftClient.getInstance().player.dropStack(stack);
            }
            MinecraftClient.getInstance().setScreen(new AhScreen(Text.empty()));
        }
    }
}

for? idk

public class ClientNetworking {

    public static void sendItemClickPacket(ItemStack itemStack) {
        ClientPlayNetworking.send(new ClickPayload(itemStack));
    }

}
