appear in discover

Hi there,

Content is automatically eligible to appear in Discover if it is indexed by Google and meets Discover’s content policies. No special tags or structured data are required. Please note that being eligible to appear in Discover is not a guarantee of appearing.

In addition to the content policies above I also recommend you to read the guide at https://developers.google.com/search/docs/guides/enable-web-stories to understand how Web Stories can appear on Google, and how to enable those appearances.
