Get ros2 Service Client ID
Hi,
To give some back ground , I have multiple Service Client like this in the picture - 2nd gif. These clients will modify some variables stored in the server. Based on some unique id of the client I would like to maintain some access control to modification the variables in ros2 Service Server.
Is it possible to obtain the ros2 Service Client ID (unique_id) from ros2 Service Server once it receives the service request ?
