Developer Policy 8.9.c - Story Mentions
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
