How to delete markers from a ros3djs viewer?

Could anyone share an example of how to delete markers in a ros3djs viewer?

From the docs here I can see that a method is available called eraseIntMarker() however I cannot work out how to use it. In particular, it expects the marker name to be provided but I’m am not sure how to specify this. For example, I publish my marker using the following code snippet but a marker name is not specified as such - just a topic.

let imClient = new ROS3D.InteractiveMarkerClient({
                ros : this.ros,
                tfClient : tfClient,
                topic : '/my_interactive_marker_topic',
                camera : viewer.camera,
                rootObject : viewer.selectableObjects
            });

Does this mean that I specify imClient as the name or do I extract the individual namespace and marker_id and provide that to the function somehow?

I’m really unsure how to go about this so it’d be great to see a code snippet.

I have created this function to delete PointCloud2

removeObject3D(object3D) {
    if (this.viewer === undefined)
        return -1;

    if (object3D.points.object === undefined)
        return 2;

    let parentScene = object3D.points.object.parent;
    //this.viewer.scene.remove(parentScene);
    this.viewer.scene.children = this.viewer.scene.children.filter(function(value, index, arr){ 
        return value.uuid !== parentScene.uuid;
    });

    return 1;
}

It is working by searching for the scene that his the parent of the PointCloud2 object then we remove this scene from the main scene's childs.
