Problem with INP score

Community Discussion Bug Report
1

We use Debugbear to collect RUM data. And we found that one of tawk.to scripts affects INP score.
Here is a link to this script:
https://embed.tawk.to/_s/v4/app/69e0c09cf0a/js/twk-chunk-common.js

The problem is in this code:

this.initialDocumentClick = function () {
  (t.$TawkAudioPlayer.init(), window.removeEventListener("click", t.initialDocumentClick));
}

This code calls t.$TawkAudioPlayer.init() on first “click” event and then removes it from event listener. This init() function could take more than 200ms and it causes INP issue (INP should be less than 200ms).

As a solution for such INP issues, web.dev recommends to use timeout function:

So, this small fix could solve INP issue:

this.initialDocumentClick = function () {
  (setTimeout(function () {
    t.$TawkAudioPlayer.init()
  }, 0), window.removeEventListener("click", t.initialDocumentClick));
}
