Simulation import from blender to unreal engine 5

Hello there, I’m new here

In context, I have an animation project that I make in blender but wanted to render it in Unreal Engine 5

But, for any simulation (rigid body especially) is it necessary to export and import simulation from blender to Unreal Engine or in Unreal Engine there is already its own simulation system.

If there isn’t how do you do it,

and if there is, do you just need to import the mesh from blender and then simulate it in the Unreal Engine and how much Poly count limit does the engine have ?
