Body Tracking License for Astra SDK

Hello, I am Jc Calayag, a 4th year college student, currently taking BSIT at STI College Balagtas. My group has a capstone project entitled “Kinesia: A System for Physical Therapy for Assessing Range of Motion using Astra Pro Plus Camera”. This project will be done using .NET 8.0. We are done making the Astra Pro Plus works on .NET, however, body tracking needs license. How can I get one? I tried to email orbbec but they say they can’t provide even the old version of license. I hope someone can help me because the final defense will be held on October 26, 2025.
