Cloud Storage 2 in Unity Editor

I'm currently trying to test the Cloud Storage 2 platform service in a Unity app. Currently when using 

CloudStorage2.GetUserDirectoryPath()

While in running in the Unity Editor play mode/Oculus Link I get no output, the function never returns anything. While running the app in a build on Quest and having given myself Beta Channel access in the app dashboard, the path prints out correctly. 

Is there any way to use the cloud storage functions within the Unity Editor for testing purposes or does this feature only work in builds with the correct permissions?
