Does URDFSpawner not add physics?

[takahashi-e6]

Hi

When I spawned the UR5 robot using the following steps, the physics of the UR5 were null and it seemed not to be affected by gravity.
Is there a way to set the physics when spawning?

steps:
run commands

ros2 launch webots_ros2_universal_robot robot_world_launch.py
ros2 launch webots_ros2_universal_robot robot_nodes_launch.py

Next, check 'Robot UR5e' → 'physics' in the Scene Tree on the opened webots.
