Handle dialogs with Selenium 4 when BiDi is enabled

Question

The BiDi introduced in Selenium 4 sounds interesting. But when I turn it on with options.setCapability("webSocketUrl", true); I have trouble with Alert, Model, and Prompt. The old way driver.switchTo().alert() does not work as the Alert does not show up. Seems like I have to add a listener but it means I have to change a lot of code.

I tried adding a listener from devtool but it looks cubersome and will change a lot of existing script in my tests.

 DevTools devTools = ((ChromeDriver) webDriver).getDevTools();
 devTools.createSession();
 // Listen for JavaScript dialogs (alerts, confirms, prompts)
 devTools.send(Page.enable());
 devTools.addListener(Page.javascriptDialogOpening(), dialog -> {
 System.out.println("Alert Text: " + dialog.getMessage());
 devTools.send(Page.handleJavaScriptDialog(true, null)); // Accept the alert
 });

Is there any other way?

I have the same problem. Once I enable BiDi, modal dialogs don't appear anymore.
 ChromeOptions options = new ChromeOptions();
 //options.enableBiDi(); // uncomment this line to reproduce the error
 ChromeDriver driver = new ChromeDriver(options);
 driver.get("https://the-internet.herokuapp.com/javascript_alerts");
 driver.findElement(By.cssSelector("[onclick='jsAlert()']")).click();
 // throws "no such alert" if BiDi is enabled:
 Alert alert = driver.switchTo().alert();
 assertThat(alert.getText()).isEqualTo("I am a JS Alert");
