Do you ask how to let TransformNode/Mesh stay (move & rotate with) infront of camera?

you can get for example a point in front of the camera with a given distance (here 5 unit).

let myVector3FrontCamera = camera.getFrontPosition(5);

Then create your hotsptot on this point.

mesh.position = new BABYLON.Vector3(myVector3FrontCamera.x, myVector3FrontCamera.y, myVector3FrontCamera.z);

The topic of hotspots is extensively discussed in this tutorial series so it’s a good resource too 3D for E-Commerce - Custom Experience | Babylon.js Documentation (babylonjs.com)
