How to switch to webview using Selenium chrome driver for testing chrome extensions

While testing a chrome extension, there is a webview element where the data is getting loaded.

<webview style="width: 1366px; height: 597px;" name="ngog-web-view" tabindex="-1" src="https://news.google.com"></webview>

I was able to invoke the extension through selenium code and but was not able to get to that webview context.

Any pointers on tools and directions in this regard?
