How to set nearby active indexes(hexagons) and get same active indexes(hexagons) within 1km in h3js

Question

  const activeIndexes = new Set();

  newIndexes.forEach((index) => {
    cellToVertex(index, { 'active': true });

    activeIndexes.add(index);
  });

const compactedIndexes = compactCells(Array.from(activeIndexes));

console.log('compactedIndexes', compactedIndexes);

  // Find nearby indexes
  const centerIndex = "8f60260b2ab5315";
  const k = 1;
  const nearbyIndexes = gridDisk(centerIndex, k);

const activeIndexes1 = new Set();

  nearbyIndexes.forEach((index) => {
    if (getResolution(index) === getResolution(centerIndex) && getBaseCellNumber(index, 'active')) {
      activeIndexes1.add(index);
    }
  });```

  console.log('nearby indexes', Array.from(activeIndexes1));

I need set  const newIndexes = \["8f60260b2ab5302", '8f60260b6873791', '8f60260b2364384','8f6026c99a5a812',"8f60b521ab9b471"\]; 

And searching with nearby active indexes using centerIndex = "8f60260b2ab5315". It need to check newIndexes.`
