JavaFX: How do I achieve 'no default focused button'

I'm new to JavaFX and I'm making my first application a simple hangman game, as it is something I've done before in swing.

In the game, I have constructed a keyboard, but I can't figure out how to make all of my buttons 'not focused' when the game starts, so it looks like this

enter image description here

Notice how the 'Q' is darkened. I considered a jankey approach, like having a button outside the scene that does nothing but acts as default focus button, but I would really like to know the correct way to do this. All my research has only told how to make a specific button focused.

Thanks a ton to anyone willing to help.

I think what @Sedrick mentioned is correct. You can just focus on any layout node by default.

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.ToggleButton;
import javafx.scene.layout.HBox;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class DefaultFocusDemo extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception {
        VBox root = new VBox();
        root.setAlignment(Pos.CENTER);
        root.setSpacing(20);
        Scene sc = new Scene(root, 500, 500);
        primaryStage.setScene(sc);
        primaryStage.show();


        ToggleButton btn1 = new ToggleButton("Button 1");
        ToggleButton btn2 = new ToggleButton("Button 2");
        ToggleButton btn3 = new ToggleButton("Button 3");
        ToggleButton btn4 = new ToggleButton("Button 4");

        HBox hb1 = new HBox();
        hb1.setAlignment(Pos.CENTER);
        hb1.getChildren().addAll(btn1, btn2);

        HBox hb2 = new HBox();
        hb2.setAlignment(Pos.CENTER);
        hb2.getChildren().addAll(btn3, btn4);

        root.getChildren().addAll(hb1, hb2);

        hb1.requestFocus();
    }
}

You have the right idea. Create an off-screen button and make sure it has starting focus.
