Click Activity in Chrome settings menu

I am trying to open “EXTENSION” option under Chrome->Settings-Extension
But when i checked the selectors … it not validated… But Workflow is working fine … May i know why the selectors is showing error?

You could try to navigate directly to “chrome://extensions/”, should be faster and more reliable than clicking a couple of times

Thank you… but i am trying to do multiple activities inside chrome settings menu… Like clearing browser cache, changing home page
