SharePoint News (Page) Analytics

We are using SPO and we are soon mooving to SPO Modern Portals. As our Corporate Communications would like to improve their communication with news, we need detailed insights into news-acitivity like you are getting it with common newsletter-tools. At least we should be able to see the detailed usage like you have it on site-collection level. But because news is on page level, we couldn't find detailed insights. 

Do you have any idea how to access detailed insights on page-level? Prefereably with standard functions. 

Thanks for ideas!
