Can I submit h4 EAD RFE response myself?

Got RFE on my 765 saying that I need to submit photos and passport page. I got laid off recently so my lawer prob will not cover me on this one.
So I earch online and I think I can do it myself. But I am wondering how hard it is. Do I need to prepare cover letter? Appreciate any help!

Yes you can. Create a cover letter explaining you are responding to the RFE. Include copy of RFE and the supporting documents requested and send it via the carrier they have mentioned at the specific address in the RFE.

I recommend not using USPS if possible.
