Trying to make character follow/loop a path but he can still move head?

I made a circular scene and I want the character to circle the scene on a path that loops. You should be able to have a first person view through the character and are not able to step out of the looping, but you can still move your head and watch around. Imagine it like sitting in a slow rollercoaster.

I am very new to unreal engine and I need help finding the best approach to this. Unfortunately, there are no tutorials out there so if you explain your idea, be as specific and beginner friendly as possible.

I´ve created a character following the path already with a camera attached to his head in the character blueprint but I cannot control the characters head movement (or camera movement) in any way. There is probably something wrong with the setup or blueprint but I wouldnt know what to look out for, so I better start over.

The goal of all of this is a VR scene preview, like if you had the VR glasses on you´d circle the scene but can only move your head to look around. The Scene doesnt have to be VR compatible tho, it should only solve as a preview how this could look in VR.

I attached a picture of the scene and the character blueprint.

Thank you for your help! I will attach more pictures if necessary.
