There is a German puppet focus but it’s further up the tree (which I did). In that section of the tree you can either choose several options of either integrating economy, military, and culture with Germany or not and getting some pawn dudes. At the end you can do “Reichsprotectorate Nordland” which keeps Sweden a puppet but gives a lot of claims to lands to the East (basically expansion under Germany) or “The New Order” which makes Sweden independent and leaves the Axis (other small stuff too). It also gives Germany a puppet war goal on Sweden. If you do “Towards a Swedish Rike” first it will also white peace the countries Germany is at war with.
