How to delete markers from a ros3djs viewer?

edit

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.
