Timeline pause in a process - javafx

Question

I wanna add dots to label every 0,5 seconds, but when there are three dots pause the process for 3 second, then remove the dots and start it again (3 times). I tried using this way, but it just add, not pause and not remove :
Label calling = new Label("Calling");
Timeline timer = new Timeline();
KeyFrame first = new KeyFrame(
Duration.millis(500),
a -> {
calling.setText(calling.getText()+".");
if(calling.getText().endsWith("...")){
new Timeline(new KeyFrame(Duration.seconds(3), b-> calling.setText("Calling"))).play();
}
}
);
timer.getKeyFrames().addAll(first);
timer.setCycleCount(9);
timer.play();
});

You can do
import javafx.animation.Animation;
import javafx.animation.KeyFrame;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
import javafx.util.Duration;
public class AddDotsToLabel extends Application {
#Override
public void start(Stage primaryStage) {
Label label = new Label("Calling");
EventHandler<ActionEvent> eventHandler = e -> label.setText(label.getText()+".");
Timeline timeline = new Timeline(
new KeyFrame(Duration.millis(500), eventHandler),
new KeyFrame(Duration.millis(1000), eventHandler),
new KeyFrame(Duration.millis(1500), eventHandler),
new KeyFrame(Duration.millis(2000), e -> label.setText("Calling")),
new KeyFrame(Duration.millis(5000))
);
timeline.setCycleCount(3);
timeline.play();
label.setPadding(new Insets(20));
primaryStage.setScene(new Scene(new HBox(label), 120, 40));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
