How to check if element is only Partially Visible?

From the below example i understood that **isVisible** will return true even if div element visible partially because I added **partialVisibility** prop. But is there any way i can say if div element is **partially visible** or **fully visible**?

```
const YourApp = () => {
return (

{({ isVisible }) => }

);
}
```

Start by reading the TrackVisibility component and its isVisible/partialVisibility behavior. Determine how the component currently calculates viewport visibility, then verify that the API can distinguish partial from full visibility; done means exposing and documenting a reliable distinction for the shown usage.
