I'm trying to build a Whatsapp bot in java using selenium and I'm working on a function that shows on the screen the response of a recipient that got messaged by the bot earlier.
I found the class "_2wUmf _21bY5 message-in focusable-list-item" to be fitting as it shows incoming messages but when I try to search by class name it doesn't find anything, even tried to use css selector but still nothing.
How can I locate those elements and why does it happen?
My code:
import javax.swing.*;
class Main extends JFrame {
public static void main(String[] args) {
new Main();
}
public Main() {
this.setTitle("Whatsapp bot");
this.setLayout(null);
this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
this.setResizable(false);
this.setSize(Constants.WINDOW_WIDTH, Constants.WINDOW_HEIGHT);
this.add(new MainPanel(0, 0, Constants.WINDOW_WIDTH, Constants.WINDOW_HEIGHT));
this.setVisible(true);
}
}
