A promise resolving to a function to unlisten to the event. Note that removing the listener is required if your listener goes out of scope e.g. the component is unmounted.
Example
```
import { listen } from '@tauri-apps/api/event';
const unlisten = await listen<string>('error', (event) => {
  console.log(`Got error, payload: ${event.payload}`);
});

// you need to call unlisten if your handler goes out of scope e.g. the component is unmounted
unlisten();
```
