 - `GLOBAL_ASYNC_QUERIES_JWT_SECRET` - JWT's use a secret key to sign and validate the contents. This value should be at least 32 bytes and have sufficient randomness for proper security
-- `GLOBAL_ASYNC_QUERIES_TRANSPORT` - currently the only available option is (HTTP) `polling`, but support for a WebSocket will be added in future versions
+- `GLOBAL_ASYNC_QUERIES_TRANSPORT` - available options: "polling" (HTTP, default), "ws" (WebSocket, requires running superset-websocket server)
 - `GLOBAL_ASYNC_QUERIES_POLLING_DELAY` - the time (in ms) between polling requests
