[Other issue]: Unable to run lasersacn_detector

[Avisheet]

Description

I have cloned the rmf_obstacle_detectors and other needed open-rmf repository. I have also successfully ran the demo simulations but while running the below code it's stuck at waiting to configure....

ros2 run rmf_obstacle_detector_laserscan laserscan_detector

@Yadunund can you guide me regarding this ?
So that I can work further in it

[Yadunund]

The node is a ROS 2 Lifecycle node.
it might be worth familiarizing yourself with

• Design: https://design.ros2.org/articles/node_lifecycle.html
• Demos: https://github.com/ros2/demos/tree/rolling/lifecycle

To configure and activate the node

# to configure
ros2 lifecycle set /laserscan_obstacle_detector configure

# to activate
ros2 lifecycle set /laserscan_obstacle_detector activate

I shall close this ticket. If you could open a PR to add this documentation that would be appreciated.
