Get controller battery level for Oculus Rift S in .NET

Hello,

I'm trying to retrieve the controller battery level of my Rift S stations to be displayed in an aggregated dashboard for easy monitoring. I tried using the C++ library and create a wrapper around it to use in my project, but I can't find any references to a battery level method.
Is there another way to achieve that? Or any pointers (huhu) on how to achieve this with the native C++ SDK?

Thanks in advance!
