How to get Instagram Messaging Bot approved?

I am trying to figure out how to approve an Instagram app which use instagram_basic and instagram_manage_messages.

I have created an app that offers to my customers a system to order and choose a Pick & Collect solution in my shops.

The app is working well in development mode but I keep getting rejection by Facebook Review team and I can't figure out why.

For instagram_basic, I have added this video: https://youtu.be/3kTJw-xegsY

And for instagram_manage_messages, this one: https://youtu.be/jvzUNG4q9qU

Any help would be greatly appreciated!
