Citizenship

I filed N 400 ( marriage based 3-year )through my attorney. My application was delivered on 02/22/22. He only included copies of Green card (front and back) and a copy of the dismissed case. I provided him with many supporting documents, but he said we do not submit those documents, and they do not need to be submitted. They are just brought to the interview in case they become necessary. However, after reading many posts on the forums, I found that many people recommend sending supporting documents along with the application. I was wondering, after sending the petition by mail, is there a possibility to upload the documents using USCIS online Account? Is it recommended to upload the supporting documents or just take them to the interview? I am concerned that my case might be delayed because my lawyer only sent copies of the green card and case dismissal document. I feel that if I provide more documents, it might help avoid case processing delays and RFE. Please advise
