How to import pftrack camera into Unreal?

I’m working in a composition where a live footage with camera movement will be surrounded by a virtual animated 3D scenario. I’ve tracked the footage using Pftrack and I want to generate my 3D scene using Unreal. How can I import the pftrack data to an Unreal camera?
My first try was to import the camera into Blender, transfer the animation to an ordinary object there and export it to Unreal (fbx). It worked, but I don’t know how to make an Unreal camera use the same animation.

Hi! did you found a way to do this ? doing the exact same research to see if Unreal is usable for a similar pipeline.
