How to access launch_ros_xxx node generated from ComposableNode launch file
When I create a launch file for a ComposableNodeContainer, a launch_ros_xxx node gets created. This can be seen when running the launch from this tutorial.
Is there a way for this launch_ros_xxx node to not get generated? Why is it generated? If I create a launch file with standalone nodes i.e. not composable nodes, the launch_ros_xxx node is not generated.
If there is no way to avoid creation of this launch_ros_xxx node, then is there a way to access this node, specifically the ability to set it's log level. The reason I need to do that is there are some discovery warnings in my system that I want to suppress.
