Limiting RPLidar S2 Scan Angle

[AlfonGio]

Thank you for the brief guide to integrate the hardware with ROS2.
I am just wondering how can I limit the scan angle_min and angle_max, I tried to add the parameters section but I think it still behave the same.

My launch code snippet:
Node(
package='sllidar_ros2',
executable='sllidar_node',
name='sllidar_node',
parameters=[{'serial_port': serial_port,
'serial_baudrate': serial_baudrate,
'frame_id': frame_id,
'inverted': inverted,
'angle_compensate': angle_compensate,
'angle_min': angle_min,
'angle_max': angle_max,
'scan_mode': scan_mode}],
output='screen'),

I am running Ubuntu 20.04 and ROS 2 Foxy Fitzroy on RPLidar S2

Is it can limit the angle?
