How to convert a "static mesh actor" imported from sketchup 2018 to a physic object?

Hello.
I imported a 3D model from sketchup 2018 with datasmith and i would like to make this model physic but the button “simulate physics” is disabled and it doesn’t change if i add “newPhysicalMaterial” into “phys material override”.
Thanks in advance.

does it have collision?
