The WebInspector.sendOverProtocol method provides an easy mechanism to test
and debug protocol commands. It's intended for developer debugging only.

Examples:

    WebInspector.sendOverProtocol('Emulation.setDeviceMetricsOverride', { ... });
    WebInspector.sendOverProtocol('Emulation.clearDeviceMetricsOverride');

    WebInspector.sendOverProtocol('Page.captureScreenshot')
        .then((err, result) => console.log(result));
