AR development question

I was wondering if someone in the community could help me with an issue I'm facing for a AR project.

I'm using a library for tracking key face/body points, from those key points I'm trying to apply Three.js and react-three/fibre to add 3d models for a virtual try on experience.

The current issue I'm facing is in regard to the camera loading. I need the core web camera to be used in these three libraries simultaneously, without using their own camera features, because they are clashing/causing conflictions which inturn is causing the camera not to load.

Any help would really be appreciated.
