How to activate Mechanical Interface AI tool R26x?

Hello community,

I downloaded the R26x 3DX Cloud and I can't see the new mechanical interface tools in CATIA assembly design (I have M3S role).

I have Part Design PLUS and Generative Shape Design PLUS, but somehow Assembly does not show the AI features. I can't find the option in preferences. I'm on the latest HF 0.10.

Does anyone have similar behaviour?

Thanks in advance, Maxime
