Get App Handle in on_window_event in WebviewWindow

[RMadsenG]

Hello,
How do we get the App Handle within on_window_event.
I am trying to attach an on_window_event to only one window in my tauri app and I need to use the AppHandle within it.

I am creating the window with WebviewWindowBuilder::from_config but the closure does not have the app handle like tauri::Builder does.

Here is the how I am creating the window.

tauri::WebviewWindowBuilder::from_config(app, config).unwrap().build().unwrap().on_window_event(|event| match event {
            WindowEvent::Destroyed => {
                // Get app handle and do stuff
            }
            _ => {}
      });

Things I've tried:
Importing use tauri::Manager
WebviewWindowBuilder does not have on_window_event, only WebviewWindow has it.
I see a similar question in #4682 #7389 for System Tray, but the event parameter in WebviewWindow has type &WindowEvent and does not have the event.window() function.

Any help in getting the handle would be greatly appreciated.
Thank You

You can get an AppHandle outside of the event handler and move it inside

let handle = app.app_handle().clone();
tauri::WebviewWindowBuilder::from_config(app, config).unwrap().build().unwrap().on_window_event(move |event| match event {
            WindowEvent::Destroyed => {
                handle.do_something()
            }
            _ => {}
      });

Thanks.
This is a simple solution I can use elsewhere in my project
