Read Network Traffic with javascript and selenium

Question

I want to read network traffic of my webpage ('some url') with javascript and selenium web driver. I have my code here:

let driver = await new Builder().forBrowser('chrome').build();
    await driver.manage().setTimeouts( { implicit: 30000 } );
    await driver.get("url...");

and with driver I want to read network traffic. I suppose is with DevToolsProtocol but i don't know how to do it with Javascript.

I have tried something such as driver.sendAndGetDevToolsCommands('something'), but i don't know how to continue.
