Where and How do I make the car damage physics?


I am a self - learning indie video game developer and I am using Unreal Engine 4.22 to make the game. In my game I am currently developing vehicles; the AI soldiers need transportation. Now, I am making the vehicles in Blender and I do not know where and to make the car damage physics. What I mean is that if a vehicle hits a tree in my game, there is visible damage at the front in the grille /bumper of the vehicle.
