Explode Animation not available only Rotate - .Step file

Hello,

I have an assembly made inside of Fusion 360. I am able to export as .Step or .Iges

I'm trying to make animated explosion view but the wizard only offers me a "rotate" option, the rest are grayed out.

I am however able to manually explode the parts of the assembly. Is there something i am missing or is the issue related to working with .step or .iges files?

Thanks!
