Question Humanoid avatar using Mediapipe BlazePose

I am making an exercise game using Mediapipe's BlazePose in Unity through BlazePoseBarracuda (https://github.com/creativeIKEP/BlazePoseBarracuda). I am using a HMD, but not the hand-held controllers. I am trying to map the output of the pose landmarks from BlazePose to the joints of an avatar that I want to use to represent the player. However, I am struggling as all the examples I find use the position of the controllers to get the hand positions. Any suggestions on how I can do this without the use of controllers? I am taking inspiration from this project: https://github.com/maceq687/FullBodyPoseEstimation

Thanks in advance!
