Holistic Skeleton Tracking

Good morning, I was writing because we are doing a research project with the use of nuitrack for bodytracking and we were going to use a multi-sensor system for recognition and we found the following link in which the Holistic Skeleton Tracking was named (How do I merge data from multiple sensors in unity?) and @a.bragin said that there was a Beta in case we could have access to it and use it.
Our case is using nuitrack version 0.37.24 but we want to use it using Unity with version 2021.3.14f1 and using Orbbec Astra Pro cameras and an Intel Realsense D455.
In case there is an increase or improvement of any version we can plan to upgrade it, in case if there are minimum requirements in software or hardware.
If you can help us it would be appreciated, thanks and best regards.
