How to match CesiumJS camera to Unreal side?

Hi!

We would need help urgently to this issue: We have a certain view and camera in Cesium JS and we would like to replicate that exact same camera position and orientation in Cesium Unreal.

We are doing ok with camera position already but then the orientation is very hard to get right. Could anyone know if there are some ready-made functions in C++ UE to do this?

only this one rotate?
