I want to create a third-party VPN app by using the library com.wireguard.android:tunnel (1.0.20211029) Can anyone help me to provide me any good resources or guide me?

In my app I am importing .config file from file manager now how to connect that file to server using tunnel library . I am using java .

I did followed https://github.com/WireGuard/wireguard-android but The app wraps a lot of the tunnel library code. I am looking for a simple example of how to use the tunnel library directly without all the wrapping with TunnelManager and ObservableTunnel.

Please guide me
