Help with getting clipboard permissions working on iOS

[miketwenty1]

Would anyone be able to help me know how to get this work on iOS? This currently works with android and desktop.
This code below is currently running within a bevy system.

let _task = spawn_local(async move {
    let window = web_sys::window().expect("window");
    let nav = window.navigator().clipboard();
    match nav {
        Some(a) => {
            let p = a.write_text("this text copies to clipboard on android and desktop but not iOS");
            let result = wasm_bindgen_futures::JsFuture::from(p).await;
            match result {
                Ok(_) => info!("copy worked"),
                Err(e) => info!("copy fail {:?}", e),
            }
        }
        None => {
            warn!("failed to clippy the clipboard clip clip");
        }
    };
});

The error is JsValue(NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.
