Hidden Traits

I hope you guys don’t mind me clarifying in here but if I’m trying to make a sim an npc maid for example, then is it two separate cheat commands?

So, while the sim is selected:

careers.add_career Adult_NPC_Maid traits.equip_trait isMaid

Or is it:

careers.add_career Adult_NPC_Maid

Then separately in another cheat window:

traits.equip_trait isMaid

Then either way I assume you make them unplayed in manage households.
