SharePoint online news posts

Dickie1305 when you post a news story the news web part will put it first in the list so users will know that it's the most recent story. There is no way out-of-the-box to flag it as "new".

Also there isn't a button or web part where the user can prove they have read the item. You could send them a link to the story via an approval flow in Power Automate and once they click the submit button in the email the flow saves their details and the details of the item they "read" to a list in SharePoint. We use this method for safety notifications where users have a requirement to read them and we have to show they have clicked the Submit button in the approval email.
