Example for how to access value action_result.result->objects[0].object.primitive_poses[0].position.x, from within PickAndPlaceTrajectory class

I have successfully triggered the simple_grasping action server and received a response with a detected object, however, I am unable to access the result of the action server programmatically. Is the task for 5.8 to create a ROS publisher for the target position x and y and a ROS subscriber to guide the pick and place with perception?
