        This API returns a `task-id` (see the response schema and the example below),

        then you need to call `/v1/tasks/{task-id}/websocket/control` and `/v1/tasks/{task-id}/websocket/stdio`

        (also `/v1/tasks/{task-id}/websocket/stderr` if `split-stderr` is true) with the returned `task-id`.'
