Java in Unity

Hi, while viewing a test rewarding ad Google in the Log writes:
Use RequestConfiguration.Builder().setTestDeviceIds(Arrays.asList(“76F2A5E6577BA309EBF303616F70485A”) to get test ads on this device.

This is Java, what can be replaced in Unity without resorting to Android Studio?

I have no experience with this whatsoever, but i think this is the page you are looking for: Enabling test ads  |  Unity  |  Google for Developers
