Webxr camera start at different position than in normal view position

I have this as a camera

 const camera = new THREE.PerspectiveCamera(
        window.innerWidth / window.innerHeight,
    // camera.position.set(0, 0.0, 0)
    camera.lookAt(0, 0, 0)

and I am adding this to the group

    user.position.set(0.0, 0.3, 0.0)
    // user.rotation.copy(camera.rotation)

and for some reason, my camera is on top of the house and house’s floor lies in origin and house height is more than 2.

On normal mode, this opens like this:

and i add this camera to the group
