Add Ping Button for Web Sockets

One of the control frames for web sockets are ping and pong messages as described in the [mdn web docs]( and in [section 5.5.2 and 5.5.3 of RFC 6455]( Closing the socket also uses a control frame which is sent if you click on the Disconnect button in Insomnia. Would be great, if there is also a Ping button to check the connection to the server. What do you think of it?
