Typo on EAD what to send, confused?

Hi,

I recently got approved for both. However, I have a typo in my name but I am unclear about what documents to send back. Here's the list of what I am sending:

1) EAD card
2) photocopy notice of I-765
3) passport picture ( as evidence)

I am confused about what they mean by "employment authorization document"? I tried the search bar but haven't found any 'list' of what to send back. Any help would be appreciated, thanks.

What do you mean?? The employment authorization document is the ead card.

Oh thank you.
