I have an SVG eye image. And I want to animate iris and the pupil to move around eyeball according to mouse position. I have already this:

SVG in html:

```js
const leftPupil = document.getElementById("left-pupil");
document.addEventListener("mousemove", function(e){
    let x = e.clientX;
    let y = e.clientY;
    leftPupil.setAttribute('transform', `translate(-${x},-${y})`);
});
```

```html

and the pupil is moving, but I don't know how to make it move only on the specific field (an eyeball).
