How do I see OPEN RATE on my express document?

Hello! We created a weekly newsletter for employees through Express in 2022 that was a template (I don't know which one). Before the new Adobe Express update last year, it would show how many people opened the document when you look at the little preview icon of the file--it was always to the right of the word "Webpage". That has since disappeared and I can't see anywhere how to find it. (Even in the help forums). Thanks for your help.
