I140 approval notice in soft copies from USCIS

My i140 is approved as per the USCIS status from their website and it says approval notice will be emailed. I have applied i140 through premium processing as my H1B is getting exhausted on 22nd of April 2022.
Hence request any one has information whether the attorney gets the documents from USCIS in the form of soft copies(Approval notice) if the case is submitted under premium processing.
I need to submit my H1B extension base on the approval notice, hence any information in this regard would be highly appreciated.
Thanks in advance.

Check with your attorney. They keep the original copy but should have received approval email.
