AR physics simulation in Unreal Engine for ARCore

Hello I have strange topic to discuss, I wanted to connect image tracking with physiscs simulations in ARCore.

I’m using Unreal Engine 5.1.1 . Everything worked good as far I turn on physiscs in Unreal Engine for one of the static mesh component inside my Actor. It worked but the object is attached to phone camera movement so it’s somehow interactive. I tried the same in Unity instead and the physiscs is working only in scope of “prefab” of image that I tracked. I assume unreal is handling the physisc and world aligment tottally different way? Does anyone know how to make physiscs calculation so it wouldn’t be interactive?

I tried to investigate Unreal Engine code for it, but I am not sure which modules I should look into for physiscs in AR ?
