Vive Wave XR Plugin does not compile with Unity 2020.2 & XR Plugin Management 4.0.1

[Fangh]

Hello.

I have started a Unity 2020.2.6f1 project.
Then I downloaded XR Plugin Mangement 4.0.1 (also tried with 3.2.13)
Then I added the scoped registry.
Then I downloaded Vive Wave XR Plugin 1.0.1
Then it does not compile.
