MaxPriorityQueue in JS runtime fromArray is not a function

As per the supported runtime for different languages in https://support.leetcode.com/hc/en-us/articles/360011833974-What-are-the-environments-for-the-programming-languages-, I am using https://github.com/datastructures-js/priority-queue#fromarray as this is a function of the supported library.

However, when I use

const maxHeap = MaxPriorityQueue.fromArray(nums);

I get an error

Line 11 in solution.js
  const maxHeap = MaxPriorityQueue.fromArray(nums);
                                   ^
TypeError: MaxPriorityQueue.fromArray is not a function

    at node:internal/main/run_main_module:17:47

This is in accordance with the example provided https://github.com/datastructures-js/priority-queue#js-3

I think it is kind of late to answer, but I'm going to answer anyway because I was facing the same issue.

The problem is that Leetcode uses version 4.1 of the library, and in this version, the fromArray doesn't exist yet.

Sadly, from what I looked up, there's no alternative to that method.
