Hi -- That Edit button only appears when the browser detects that the story owner (you) or an admin in your organization is signed in. Try signing out of your account or opening your web page in an incognito/private browsing window and the button won't appear.
I believe that the &edit in the url is what adds the edit capability. Can you remove the &edit and repost?
