How to use IKSolver in utils/control_utils.py to solve joint angles for R1Pro？

I want to solve the angles of each joint of the robot arm by inputting the end pose of the robot arm.

When defining the IKSolver, I use：

> robot_description_path=robot.robot_arm_descriptor_yamls[self.arm_name]

But I got an error:

> AttributeError: 'R1Pro' object has no attribute 'robot_arm_descriptor_yamls'

Please tell me how to solve this problem, look forward to your reply！
