Hlo Friends,
How can I see what pages are indexed in Google?

Check with keyword: [Site:URL], if page hasn't been indexed, it'll not show in result

You can check it by this format:

site:http://www.example.com

Indexed webpages can be checked by typing SITE:URL in the search console of a search engine. The result will display only the indexed webpages of your website.

bu using "site:websitename", you can easily check the index status of your pages.
