No mention on get_link_position() and get_link_velocity() in the package

[virajawate]

    def get_ee_position(self) -> np.ndarray:
        """Returns the position of the end-effector as (x, y, z)"""
        return self.get_link_position(self.ee_link)

    def get_ee_velocity(self) -> np.ndarray:
        """Returns the velocity of the end-effector as (vx, vy, vz)"""
        return self.get_link_velocity(self.ee_link)

line 138 (xarm6.py)
The code is not correct as it does not return any value because get_link_position and get_link_velocity function are neither derived nor defined anywhere in the code. The same is with line 92 (xarm6.py)

target_arm_angles = self.inverse_kinematics(link=self.ee_link, position=target_ee_position, orientation=np.array([1.0, 0.0, 0.0, 0.0]))

An update, I found these functions in panda-gym lib, but its not imported in the code.
