I think the airline you are looking for is GOODJet. I believe they are Swedish but operating from across Scandinavia to European destinations.
In April they were supposed to start A320 operations from Gothenburg to Paris (Beauvais) and to Nice.
In June they were supposed to start:-
Malmo to Paris and Nice
Stockholm (Skavsta) to Paris
Oslo (Torp) to Paris
I don't know if any or all these services started.
