Livox HAP IMU extrinsic and intrinsic information

[YoungsooH]

I found that LIO-Livox does not use IMU in HAP mode.
There are only identity matrix and covariance and bias values.
I want to use IMU information in Livox HAP TX IMU model.
Where can I get imu information ( covariance, bias, LiDAR-IMU extrinsic matrix)?
