Multiple windows with different menu not working as expected

[shalapatil]

I am working on tauri app with next js.

    tauri::Builder::default()
        .setup(|app| {
            let app_handle = app.handle();

            // Create the "main" window with its menu
            let main_window = WindowBuilder::new(
                &app_handle,
                "main".to_string(),
                tauri::WindowUrl::App("/".into()),
            )
            .menu(create_main_menu()) // Attach the main menu
            .visible(false) // Hidden by default
            .build()?;
            println!("Main window created: {:?}", main_window);
    
            // Create the "onboarding" window with its menu
            let onboarding_window = WindowBuilder::new(
                &app_handle,
                "onboarding".to_string(),
                tauri::WindowUrl::App("/onboarding".into()),
            )
            .menu(create_onboarding_menu()) // Attach the onboarding menu
            .build()?;
            println!("Onboarding window created: {:?}", onboarding_window);
    
    
            Ok(())
        })
        .run(tauri::generate_context!())
        .expect("error while running Tauri application");

Onboarding window is created at last. onboarding menu is only getting shown for main window as well.

What could be the issue?

thank you!
