extrinsic_calibration_manager package is missing

[ahsan155]

I am trying to do sensor calibration. I already created vehicle and sensor model. Then I came to this link https://autowarefoundation.github.io/autoware-documentation/main/how-to-guides/integrating-autoware/creating-vehicle-and-sensor-model/calibrating-sensors/extrinsic-manual-calibration/. Instruction in this documentation uses extrinsic_calibration_manager package but this package is not present autoware. I cloned CalibrationTools repositories and built autoware. extrinsic_calibration_manager is still not there. Is the documentation outdated? If so, what should I use in place of extrinsic_calibration_manager?
