Isaac Simulator IMU Sensor noise parameter

hello! Do you know how to set the noise data of IMU now? Can you run orbslam3 successfully? I am currently running orbslam3’s monocular-IMU and Vins-Mono using ISSAC SIM. But none of them worked. I am not sure if it is the problem that IMU needs to be calibrated. So do we need to calibrate IMU in Issac sim? Or do you have a solution?
