RFE on H4 EAD reply

My wife received RFE asking for more documents on her H4 EAD application. We had applied through attorney. The attorney now charges more to reply for an EAD or else I need to reply the RFE myself. My question is, what is needed along with the documents to reply the RFE? Can somebody please brief me the process of replying the RFE myself?
Thanks for your help

Nothing else is needed to reply to RFE except the requested documents.

You can send it by mail yourself and save money.

I am also in the same boat, I received a RFE for my Spouse EAD , standalone First time applicant. The RFE is asking to provide the H-4 Approval notice receipt number which is the I-797, but they haven’t listed any address on the letter do I need to send it to the address listed on the top right hand corner of the letter .And what all the documents Do I need to attach while sending
