Possible workaround for authentication in Unity project on IL2CPP backend?

Hey, so we are using a plugin called Spotify4Unity that uses SpotifyAPI-NET for our Unity project. When the scripting backend is set to IL2CPP, authentication seems to fail and I have manged to trace it down to SpotifyAPI Auth’s calls to System.Diagnostics to open a browser. Unfortunately, Unity does not seem to support calls to to System.Diagnostics if the scripting backend is set to IL2CPP, this was confirmed by a Unity Developer: https://forum.unity.com/threads/solved-il2cpp-and-process-start.533988/

I am wondering if there is a workaround for this? The Unity developers say that they do not know if or when support for it will be added. Thank you.

Here’s the log output when attempting to open the browser (if that’s useful):

Can’t promise a fixed response date, but be assured I will have a look at the repo and will come back to you @benlane2003 😃

I added a link.xml file attempting to stop Unity from stripping anything from the SpotifyAPI and Newtonsoft.Json assemblies and am now getting a different error. Here is the simple project i set up. I made it initialize with the “1” key and open the login URL with the “2” key. When it Authenticates and logs in it should just print out the name of the Spotify Account. https://github.com/benlane2003/SpotifyTest
