Listing firebase storage images with js

I am trying to recover the images that I saved in the firebase storage, but without success.

<script>

// Get a reference to the storage service, which is used to create references in your storage bucket
var storage = firebase.storage();

// Create a storage reference from our storage service
var storageRef = storage.ref("images");

// Create a reference under which you want to list
var listRef = storageRef.child('/screenshot/c5BRECcYHPOfyLXKzYFNCu9Wd9a2');

</script>
