How to chage notification position?

Hello,

is it possible to change notification position? Right now notification appears in the middle of my page. Where can I change it?

    @Override
    public void showLoginFailure() {
        new Notification("Login Error",
                "Please write a correct password.",
                Notification.Type.WARNING_MESSAGE, true)
                .show(Page.getCurrent());
