MaterializeCSS Modal Not Opening

This is my HTML code for Modal:

<div class="modal">
  <div class="modal-content">
    <h4>Modal Header</h4>
    <p>A bunch of text</p>
  </div>
  <div class="modal-footer">
    <a href="#!" class="modal-close waves-effect waves-green btn-flat">Agree</a>
  </div>
</div>

And this is how I am referencing it in JS:

function aFunction() {
    var elem = document.querySelector('.modal');
    var instance = M.Modal.getInstance(elem);
    instance.open();
}

I am calling the function on button click but the modal doesn't show up. The only change I notice is that scrollbars on the right disappear.

Which version are you using?

This is how it is done in example the docs for v1.0.0:

document.addEventListener('DOMContentLoaded', function() {
  var elems = document.querySelectorAll('.modal');
  var instances = M.Modal.init(elems);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/materialize.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/css/materialize.min.css" rel="stylesheet" />
<!-- Modal Trigger -->
<button data-target="modal1" class="btn modal-trigger">Open the modal</button>

<button class="btn">Do something else</button>

<!-- Modal Structure -->
<div id="modal1" class="modal">
  <div class="modal-content">
    <h4>Modal Header</h4>
    <p>A bunch of text</p>
  </div>
  <div class="modal-footer">
    <a href="#!" class="modal-close waves-effect waves-green btn-flat">Agree</a>
  </div>
</div>

Or if you want to open it programatically (via your own functions), you need to init the modal first.

document.addEventListener('DOMContentLoaded', function() {

  var elems = document.querySelectorAll('.modal');
  var instances = M.Modal.init(elems);
  
  var singleModalElem = document.querySelector('#modal1');
  var instance = M.Modal.getInstance(singleModalElem);
  const modalbtn = document.querySelector('#open')
  modalbtn.addEventListener('click', () => {
    instance.open();
    // Do other stuff
  })
});
<link href="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/css/materialize.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/materialize.min.js"></script>
<!-- Modal Structure -->
<div id="modal1" class="modal">
  <div class="modal-content">
    <h4>Modal Header</h4>
    <p>A bunch of text</p>
  </div>
  <div class="modal-footer">
    <a href="#!" class="modal-close waves-effect waves-green btn-flat">Agree</a>
  </div>
</div>

<button id="open">Open a single modal</button>
