Topic: Dragon Quest Treasures - code mystery option entry?

I notice but maybe others that there is a section one you get to save the game and look at your in-game menu there is a option to enter a Code aka Pokémon mystery code entering. So does this mean we will get DQT codes in the future or have to buy codes for items?

Here are two codes:

YUB – Reward: A King Slime voiced by Dragon Quest series creator, Yuji Jorii (NEW)
PEK – Reward: A Killing Machine voiced by VTuber Usada Pekora (NEW)
