Hey Nejra, the simplest way to accomplish this is by using another IAS within the one you're already using this. Make a simple "ConfirmDialog" with just a cancel/confirm button and display some text. I made a sample below:

public class ConfirmDialog : Dialog
{
public ConfirmDialog(IEngine engine, string message) : base(engine)
{
// Init widgets
Label = new Label(message);

// Define layout
AddWidget(Label, 0, 0);
AddWidget(CancelButton, 1, 0);
AddWidget(ConfirmButton, 1, 1);
}

public Button CancelButton { get; } = new Button("Cancel") { Width = 100 };

public Button ConfirmButton { get; } = new Button("Confirm") { Width = 100 };

private Label Label { get; set; }

public static bool ShowMessage(IEngine engine, string message)
{
bool confirmed = false;

try
{
var dialog = new ConfirmDialog(engine, message);
dialog.CancelButton.Pressed += (sender, args) =>
{
confirmed = false;
engine.ExitSuccess("Close");
};

dialog.ConfirmButton.Pressed += (sender, args) =>
{
confirmed = true;
engine.ExitSuccess("Close");
};

var controller = new InteractiveController(engine);
controller.ShowDialog(dialog);

return confirmed;
}
catch (ScriptAbortException)
{
return confirmed;
}
}
}

This could be called by doing ConfirmDialog.ShowMessage(engine, "Are you sure you want to perform the operation?") which should then return the boolean of if it was confirmed or not.

Minor note: make sure you're using the InteractiveAutomationScriptToolkit nuget library.
