I'm using the code below to do so but it doesn't work. The Page.enable message is not sent to the browser. What am I doing wrong? var transport = page.Connection.Transport as WebSocketTransport; var message = new WebSocketTransportTask { Id = 5, Method = "Page.enable" }; await transport.ScheduleTransportTask(message);31var transport = page.Connection.Transport as WebSocketTransport;32{33};34await transport.ScheduleTransportTask(message);
