There are a number of ways to wrap native code libraries as a managed library. I did it once (packaged an Obj-C library as a .NET DLL for a Xamarin app) back in 2018 but had lots of help from a teammate who knew that dance far better than me and I forgot all of the details. I googled and found at least four different blogs posts showing how to do it.

I know that's not an answer but if you're feeling adventurous you might be able to help the project.
