Hi Max, welcome. I've never done it but I think you'd just have to pull off one of those rosettes, right back to its base, and put it into some gritty compost, water it and see what happens. I know they like the sun but as cuttings it might be too much for them and they'd need a bit of shade. Tell us how you get on.
If someone else tells you something different, believe them. I'm no expert. A bit of a bung it in and see what happens gardener
