Sceneform - Getting Vector3 position from screen pixel position?

The Sceneform camera has the camera.setWorldPosition method which accepts a Vector3.

I have currently calculated the center point of where the user pinches the screen using the ScaleGestureDetector.

My question is, how can I calculate the Vector3 position I want to move to based a single point on the screen?

Let's say the user pinches near the middle of the screen --- the ratio for the X and Y coordinates calculated from the phone's display metrics are

X: 0.58122176, Y: 0.46196362

How do I convert it into a Vector3 so my SceneView camera can zoom in that position on the screen?

 private class ZoomGestureDetector extends ScaleGestureDetector.SimpleOnScaleGestureListener {
        @Override
        public boolean onScale(ScaleGestureDetector detector) {
            
            float ratioX = detector.getFocusX() / displayMetrics.widthPixels;
            float ratioY = detector.getFocusY() / displayMetrics.heightPixels;

            Log.d(TAG, "onScale: Called X: " + ratioX + ", Y: " + ratioY);

            Camera camera = sceneView.getScene().getCamera();
            //camera.setWorldPosition(); <--- How to calculate vector3

            return false;
        }

        @Override
        public boolean onScaleBegin(ScaleGestureDetector detector) {
            isScaling = true;
            return true;
        }

        @Override
        public void onScaleEnd(ScaleGestureDetector detector) {
            isScaling = false;

        }
    }
