I would add.

If you want to record only your own stream, use `?useRemoteRecorder=false`; if you want to record the other party's stream as well, use `?useRemoteRecorder=true` as a parameter to the URL.

The URL that confirmed the Safari application crash is strictly the following URL.
- https://yuki-uchida.github.io/firebase-webrtc-sample/?useRemoteRecorder=true
We have not confirmed the case of `useRemoteRecorder=false`, but it will probably take longer to crash.
