No.

You cut the hole where the outlet will be.

You feed romex wire down from the attic to that hole (ideally with metal sheath).

The part at the circuit box is important to do and do properly, but doesn’t pertain to your question, so I won’t get into that.

Then you insert a box in the drywall hole and feed the wire into the box. Secure the box to the stud/backside of the drywall. Attach the wires to the receptacle and secure it in the box. Install a cover plate (adjusting the 4 metal tabs at the receptacle corners with pliers may be necessary for it to sit flush).

And that’s it. Except for the circuit box part. But don’t attempt that as a layperson.
