ContainPlugin in Gazebo 9 Not working

edit

I need to use the Contain plugin provided by Gazebo itself on gazebo 9.8.0. However, after following the tutorial here: http://gazebosim.org/tutorials?tut=co... . I observed that it is not working. It says that "In gazebo 9 and beyond the gazebo topics are removed; only the ignition transport topics are available." but there are no examples neither tutorials for the ignition transport topics for such plugins. Can you share if there are any tutorials that i can follow. It would be appreciated.
