Why are there no Kadabra or Alakazam physically seen as catchable NPC Wild Pokémon in Pokémon UNITE?

I knew that Abra are physically seen as catchable NPC Wild Pokémon in Pokémon UNITE. However, in this game, Kadabra and Alakazam aren’t catchable NPC wild Pokémon, although Abra can’t evolve into anything, not even into Kadabra or Alakazam. Now I wonder why you think that Kadabra and Alakazam are not physically seen, not even as catchable NPC Wild Pokémon at all in Pokémon UNITE?
