Three js VR video angle change gyroscope

Question

Three js has this example: https://threejs.org/examples/webxr_vr_video.html But the angle doesnt change perspective when you move the phone around unless you enter VR mode.

I am looking for a way to make video behave in mobile browser as demonstrated here: https://bitmovin.com/demos/vr-360 When you move mobile phone around you can see different angles of the video (that is before you even enter VR mode by clicking glasses icon).
