#[tauri::command]
fn open_devtools_window(app: tauri::AppHandle<Wry>) {
    #[cfg(debug_assertions)]
    {
        if let Some(win) = app.get_window("devtools") {
            let _ = win.set_focus();
            return;
        }

        let main_window_config = &app.config().app.windows[1];
        let _ = tauri::window::WindowBuilder::from_config(&app.clone(), main_window_config)
            .expect("[Err] failed to compose WindowBuilder from config")
            .build()
            .expect("[Err] failed to build WindowBuilder from config");
    }

Make the command an async fn - ref https://docs.rs/tauri/latest/tauri/webview/struct.WebviewWindowBuilder.html#known-issues
