Is the brake command being implemented in the ros2 driver wrapper?

[TZECHIN6]

According to the SDK:

void HunterRobot::ActivateBrake() {
  auto hunter = dynamic_cast<HunterInterface*>(robot_);
  hunter->ActivateBrake();
}

There should be a command for braking and releasing the brake of hunter robot. However, I could not find this implemented in the ros2 driver, only SetMotionCommand and status callback are included. Might I know is that the braking function is not applicable for hunter robot, or its just simply not implemented?
