emits from localhost are not getting picked up by main window

heyo
i have this auth window for Twitch that basically has to redirect to a link on localhost, so it goes back to like http://localhost:3030/oauth_twitch.html
i'm trying to emit the token back to the main window, but the event isn't getting picked up by the listener
i listen on the webviewWindow but also tried event.listen

main window

async login() {
  [...] (generating the url)

  const auth_window = new WebviewWindow("oauth_twitch", {
    url: link.toString(),
    width: 600,
    height: 600,
    title: "Twitch",
    devtools: true,
  });
  auth_window.once("tauri://created", () => {});
  auth_window.once("tauri://error", (err) => toast.error(`Error creating window: ${err.payload}`));

  const thisRef = this;
  const handleEvent = (event: Event<string>) => {
    toast(`got event with key ${event.payload}`);
    thisRef.#state.data.token = event.payload;
    thisRef.connect();
  };

  const unlisten = await auth_window.listen<string>('twitch_auth', handleEvent);
  unlisten();
}

oauth_twitch window (after redirect)

const parsedHash = new URLSearchParams(window.location.hash.substring(1));
const access_token = parsedHash.get('access_token');

const tauriWindow = window.__TAURI__.window.getCurrentWindow();
tauriWindow.emit("twitch_auth", access_token).then(() => console.log("token sent"));

i get "token sent" in this other window, and nothing in the main window
no errors on either side

also tried to emitTo to the main window, didn't work either
am i a complete moron? x)

ok i was being a moron
basically i thought the listen would await until getting a response, and then it would unlisten, but the await is to setup the listener?
anyway i passed the unlistener to my object and accessed it with thisRef inside handleEvent

i don't know if you're supposed to do it that way, cause there might be some obscure case i'm not thinking about where the function can exit without unlistening but not a huge issue i guess
