JavaScript refactoring a function using reduce - javascript refactoring with function

I've written a function to turn a string such as 'aaazeeeee' into a new string of 'aaa z eeeee'

this is the code I've tried that works

const groupCharacters = signature => {
  let newSignature = "", arr = [];

  let result = [...signature].reduce((accumulator, element, index) => {
    // check if last element in accumulator matches current element
    if (accumulator[accumulator.length -1] !== element) {
      // push accumulator into array
      arr.push(accumulator);
      // set newSignature as new element
      newSignature = element;
    } else {
      // else add element to newSignature
      newSignature = accumulator += element;
    }
    
    // if is last item, push to array
    if (index === signature.length - 1) arr.push(element);

    return newSignature;
  })

  return arr;
}

console.log(groupCharacters('aabaaaaa'));
