Visa Status Approved, but didn't get Form I-129

I got this information while checking my fresh H-1B visa status.
“On July 15, 2021, we approved your Form I-129, Petition for a Nonimmigrant Worker, Receipt Number SRCXXXXXXXXX. We sent you an approval notice. Please follow the instructions in the notice. If you do not receive your approval notice by July 30, 2021”
But I still didn’t receive anything by mail.
When I try to report the same in Its asking for USA address to be filled.

My question is approval notice will be send to which address? My Indian address or employer address?

Check with your employer. If you are in India the notice will be sent to your employer.
