Brand Approval Requirments

Hey everyone, I’m very new to the space and trying to get my brand name approved but I don’t know what I’m supposed to send in. The video said that I needed to send in real-life pictures of my packaging with the brand name on it, a barcode, and a label. But I don’t know where to get these from, so I sent in a picture of just my plain box with my logo stuck to the front on a label. This subsequently got rejected, I think it is because I need the label to be a permanent part of the box, but I don’t know. What do you guys think?
