I am trying to view an interactive marker in a web GUI using ros3djs. I am following the tutorial here but I am not able to see any markers.

The topic I am trying to subscribe to is /twist_marker_server/update, which works on RViz. I am wondering if my problem is related to the update bit and maybe I'm subscribing to the wrong thing?

Does anyone have any ideas? Here's a code snippet:

let imClient = new ROS3D.InteractiveMarkerClient({
                ros : this.ros,
                tfClient : tfClient,
                topic : '/twist_marker_server/update',
                camera :,
                rootObject : viewer.selectableObjects

EDIT: I've just noticed in the documentation here that '/tunneled/update' is appended to the topic name I specify resulting in the above code trying to subscribe to '/twist_marker_server/update/tunneled/update', which does not exist. I thought that /twist_marker_server/update was the right topic to specify as this works on RViz. Is there some way I can stop ROS3D.InteractiveMarkerClient from appending anything to the topic name so it doesn't break it?
