Keepalive

An idle WebSocket closes automatically after 5 minutes.

Keep the WebSocket connection open by sending keepalive ping messages periodically.

The keepalive ping message would be constructed like below:

{
  "jsonrpc": "2.0",
  "type": "command",
  "method": "keepalivePing",
  "params": {},
  "id": "<COMMAND_ID>"
}
