window.chrome.runtime is undefined for selenium webdriver

Question

I am using Selenium for testing. I noticed a different behavior starting Chrome manually and starting it with selenium. After a lot of investigation I broke the problem down to JavaScript's window.chrome.runtime which is undefined if started with selenium.

After some research on Google I have found people facing similar issues, but none of their solutions worked for me.

I have tried so far to remove the test-type switch:

ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("excludeSwitches", Arrays.asList("test-type"));

Are there any other ways I can make it work?
