Trouble scraping Chrome Web Store Extension data

Describe the problem.
I can't figure out how to scrape the list of a category's extensions in the Chrome Web Store. To start with something small, I just want the extensions in the Accessible category. It's almost like there's something special about the Chrome Web Store that prevents the webscraper extension from working properly because using Select or Element Preview doesn't do anything. I ended up using Chrome's Inspect tool->Elements tab to figure out the selector path manually.

To practice with typing the selector path manually, I have successfully scraped data from one of the ecommerce test sites on webscraper.io using the same method of Chrome's Inspect tool->Elements tab, even though webscraper's Select and Element Preview work as expected.
