The car cannot move and the model cannot be displayed on rviz

[why371323]

Hi,
Thank you for open-sourcing your great work. I am running the navigation command in a simulated environment.
command： ros2 launch agilex_scout simulate_control_gazebo.launch.py lidar_type:=2d
ros2 launch scout_nav2 nav2.launch.py simulation:=true slam:=false localization:=amcl

The car cannot move and the model cannot be displayed on rviz。I see that controller_manager is not started. Is there a command missing to start controller_manager or other files or settings missing?Hope to get your reply, thank you very much
