After switching to the webview context, it will be possible switch between the different views that are visible from the Google Chrome inspector tool. You will need to switch between window handles, for example:
Iterable<String> windowHandles = driver.getWindowHandles();
for (String windowHandle : windowHandles) {
System.out.println("Window handle: " + windowHandle);
driver.switchTo().window(windowHandle);
System.out.println(driver.getPageSource());
}
