[2023] Questions about prisoners

I've set up individual cells for them with beds, workstations, food and water, it's been a couple days but they're still in the "Calm" status. They're also not equipping their class-specific equipment, even though there is enough of each item in storage.

Am I missing something? How long does the assimilation process take?

PS: I have a human settlement and my prisoners are human, a green bug-face dude and a cat guy.
