Non level up evolutions in Pokémon Quest

In Pokémon Quest how do you evolve Pokémon that don’t evolve by level up? You know Pokémon like Growlithe Kadabra or Eevee who usually evolve by trading, happiness or by stones or the like. At the moment I don’t see any way to evolve these Pokémon or have they got levels they evolve at just for this game? Any help would be greatly appreciated
