   - To use from command line: `ros2 action send_goal /camera/camera/triggered_calibration realsense2_camera_msgs/action/TriggeredCalibration '{json: "{calib run}"}'` or even with an empty request `ros2 action send_goal /camera/camera/triggered_calibration realsense2_camera_msgs/action/TriggeredCalibration ''` because the default behavior is already calib run.

+  - The action gives an updated feedback about the progress (%) if the client asks for feedback. To do that, add `--feedback` to the end of the command.
   - If succeded, the action writes the new calibration table to the flash. It also returns the new calibration table as json string and the health as float32
+  - If failed, it will return the error message inside the result. For example:
+  ```
+  Result:
+    success: false
+    error_msg: 'TriggeredCalibrationExecute: Aborted. Error: Calibration completed but algorithm failed'
+    calibration: '{}'
+    health: 0.0
