Are we able to use index.html in external window?

[Hellager]

Try use external window to display app docs which have router path /docs/:name
Follow the multiwindow guidance and works greet to show https://tauri.app/
However, if i try switch "https://tauri.app/".parse().unwrap() to "index.html".parse().unwrap() , the external window will not show and get this output

thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: RelativeUrlWithoutBase'

With "https://tauri.app/".parse().unwrap() switch to "index.html".into(), the app will be unable to compile with error:

error[E0277]: the trait bound `url::Url: From<&str>` is not satisfied
  --> src\main.rs:17:32

   = note: required for `&str` to implement `Into<url::Url>`

For more information about this error, try `rustc --explain E0277`.

So, are we able to still use index.html in external window?
If not, whats the best practise to show app docs if the app unable to connect to the internet?

Got it, just using tauri::WindowUrl::App("/doc/index".into()), my bad
