I got my iPhone as a gift, and it's locked to an owner, but we don't know apple ID

I got my iPhone SE 2020 as a gift, few days ago. And it's locked to a owner

That owner will need to unlock the phone then, since it is useless until this occurs.

Hate to break it to you, but the “gift” you were given is stolen property.

Return it to whoever gave it to you.
