Is there a way to remove a label from a primitive LabelCollection?

1. A concise explanation of the problem you're experiencing.

I'm adding a Label Collection to my scene, and i want to delete one label from my collection. (by looping)

2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

var annotations = viewer.scene.primitives.add(new Cesium.LabelCollection());

function create_notes(type,lng,lat,heightVal) {
  newGuid = Cesium.createGuid();
  var newlabel = annotations.add({
    id : newGuid,
    position : Cesium.Cartesian3.fromDegrees(lng,lat,heightVal),
    text : document.getElementById("redline_notes").value,
    showBackground : true,
    font : '14px monospace',
    horizontalOrigin : Cesium.HorizontalOrigin.LEFT,
    verticalOrigin : Cesium.VerticalOrigin.BOTTOM,
    disableDepthTestDistance : Number.POSITIVE_INFINITY
  created.label.push({"eid" : newGuid,
             "eobject" : newlabel});

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.

I want to edit/delete the text in the label,
by looping over my created json object.

4. The Cesium version you're using, your operating system and browser.

Cesium 1.52, Win 10, Chrome

You should be able to use the LabelCollection.remove method for this:
