How to use the VPN Service class in Unity?

I want to build in Unity (Android) a VPN client using the .NET library VpnService Class (Android.Net) | Microsoft Learn. Unfortunatly I can’t use the Android.App.Service class in Unity. Is there any possibility I can include that in my project?

Thank you!
