Rule 608.3b
Official source text from the 22 April 2021 Rules release
If the object that’s resolving is a copy of a permanent spell, that object becomes a token permanent and is put onto the battlefield under the control of the spell’s controller. It is no longer a copy of a spell. The token put onto the battlefield this way is not “created” for the purposes of any replacement effects or triggered abilities that refer to creating a token.
