devtools-protocol-websocket-example.js

const devtools = new WebSocket('ws://localhost:9222/devtools/page/69990451-aaab-4ef8-87b1-ea77b8101b2a');

devtools.onmessage = ({data}) => {
	const {result: {result: {value}}} = JSON.parse(data);
	console.log('WebSocket Message Received: ', value)
};

devtools.send(JSON.stringify({
	id: 1,
	method: 'Runtime.evaluate',
	params: {
		expression: `'The current URL is: ' + location.href`
	}
}));

Hi , Could you help me how to change the iframe using the websocket remote debug?
