-   - `ping` — optional boolean field. Some cloud providers (like Cloudflare, Fly.io) close the stream if client doesn't send anything during some time. As workaroud you can send same filter every N seconds, but this would be not optimal since you need to keep this filter. Instead, you can send subscribe request with `ping` field set to `true` and ignore rest of the fields in the request. Since we sent `Ping` message every 15s from the server, you can send subscribe request with `ping` as reply and receive `Pong` message.
