How to add Google News to RSS Feed Widget

I tried inserting the Google News URL directly into the RSS Feed and it always gave me an error.

After some searches on Google, I found this quick way.

#1. Suppose you enter a topic on Google News, for example: Singapore

#2. Google News will redirect you to a page with URL like this

#3. We will change URL, use this URL format

https://news.google.com/rss/topics/{id}?hl={lang}

{id} is this part

#4. We will have this URL

https://news.google.com/rss/topics/CAAqIQgKIhtDQkFTRGdvSUwyMHZNRFowTW5RU0FtVnVLQUFQAQ?hl=en-US

#5. Paste it to the RSS Feed Widget

#6. Result
