Instagram API Client Approval for Production on iOS

Looking to take my instagram api client to production so it’s not limited to 5 users.

I read the docs but still not quite sure about how the process works since it says the app needs to be in production and I need to submit a video of how the instagram integration works. So do I need to have an app in production with the sandboxed version of instagram or can i have the app in production without instagram and screencast a testflight version showing the instagram flow?
