Launch photo taken with cardboard camera in cardboard app

Hi
I have got some photos that I took with Google cardboard camera that I can view using my cardboard headset. Now I want to use those same assets in a VR demo. So from my entry level i want to be able to embed the photo into e.g. a sphere and then when i focus on it, launch the photo so i can view in the same way that I view direct.

I have managed to download the asset as a jpg for the static frame and set that as a texture, but how do i get the interactive 360 degree asset into unreal and then launch it when i focus on the sphere with the corresponding photo?

Is there anyone who can help me understand how i do that?

thanks
