I have reviewed the Google News Sitemap documentation. However, I notice that while there is a "Pages" attachment label, no actual Notion pages were provided with content. Since you mentioned I should use information from Notion pages to construct the XML sitemap, but those pages are not attached, I cannot create a complete, accurate news sitemap with actual article URLs and data.

To complete this task, I would need:
1. The actual Notion pages containing the news articles for NewDecoded.com
2. The article URLs, publication dates, and titles to include in the sitemap

Could you please provide the Notion pages or the specific article information you'd like included in the news sitemap for newdecoded.com/news?
