How to get Amazon to request the COA and GMP in a listing?

Hello, I sell a product in dietary supplement and I want Amazon to request the COA and GMP of the product, I am not the owner of the listing but I am the authorized seller, what should I do? This listing has 2 variations, one of them was asked for the COA AND GMP but the other variation was not, and it is exactly the same product, just different quantities. Any suggestions?
