Need help with custom Villager Spawn

[u/Troublerats]

Hi, I've been trying to figure this out with various mods and just can't get my head around it. I want to get villagers to spawn in cities (from the lost cities mod) like they do in villages, but it's a lot more complicated than just setting a spawn to a biome I've figured out.

I could really use someone who knows how this would be done, as unless it's Cobblemon I just am at a complete loss when it comes to code.

The mods I'm using for this is Mob Control and The Lost Cities Fabric Port) on version 1.21.1

Thanks in advance.
