We found that your app screen recording and submission notes didn't fulfill the technical requirements for use of the Story mention. Your submission should show how users will respond to Story @mentions, including how media is delivered in the app.
To resolve this issue, make sure that your submission clearly shows how the Story @mention feature will function in your app.
For more details on submission requirements please visit our app review documentation for Instagram Messaging: https://developers.facebook.com/docs/messenger-platform/instagram/app-review
