/**

* Calculates the [INP](https://web.dev/articles/inp) value for the current

* page and calls the `callback` function once the value is ready, along with

* the `event` performance entries reported for that interaction. The reported

* value is a `DOMHighResTimeStamp`.

*

* A custom `durationThreshold` configuration option can optionally be passed to

* control what `event-timing` entries are considered for INP reporting. The

* default threshold is `40`, which means INP scores of less than 40 are

* reported as 0. Note that this will not affect your 75th percentile INP value

* unless that value is also less than 40 (well below the recommended

* [good](https://web.dev/articles/inp#what_is_a_good_inp_score) threshold).

*

* If the `reportAllChanges` configuration option is set to `true`, the

* `callback` function will be called as soon as the value is initially

* determined as well as any time the value changes throughout the page

* lifespan.

*

* _**Important:** INP should be continually monitored for changes throughout

* the entire lifespan of a page—including if the user returns to the page after

* it's been hidden/backgrounded. However, since browsers often [will not fire

* additional callbacks once the user has backgrounded a

* page](https://developer.chrome.com/blog/page-lifecycle-api/#advice-hidden),

* `callback` is always called when the page's visibility state changes to

* hidden. As a result, the `callback` function might be called multiple times

* during the same page load._
