How to use fastdds_monitor on ROS2 Humble

I tried following some online tutorials ( 3. Example of usage - 4.0.0 , https://www.youtube.com/watch?v=OYibnUnMIlc, …) but cannot get any statistics. I can see my topics, just not statistics. I made sure to set FASTDDS_STATISTICS and even tried rebuilding my WS with --cmak-args -DFASTDDS_STATISTICS=ON but I’m quite sure that did nothing. I then run the AppImage (~/Apps/eProsima_Fast-DDS-Monitor-v3.2.0-Linux.AppImage) but no luck.
