Student finance = providing evidences

Hello! I’ve sent student finance my original ILR card and passport and they returned them to me last week I’ve received email from them saying that I need to send them evidences to confirm my living years. It says that they need a home office letter saying I’ve been living here 3 years continuously from 1/9/2020 or expired cards or immigration documents. I’ve got them and try to send them tomorrow. My question is do I need to send the evidences which I already sent them (passport and ID) again? Or only those documents and expired cards.
