How can I confirm or deny that my VContainer project is building using Source Generator?

[zadi0648]

I'm followed the instructions inside of https://vcontainer.hadashikick.jp/optimization/source-generator inside of my IL2CPP-enabled project. My project's .asmdef has VContainer as a reference, ect. But I'm not sure where to look for these __GeneratedInjector classes that Code Generator automatically generates (to confirm that it's happening)?

When I Build, I don't see anything that confirms or denies that Code Generator is indeed kicking in.

I've thought of one way to test it: to make a change that should supposedly break Code Generator. So I'm made some [Inject] methods private, as supposedly that shouldn't work with Code Generator. But it still built and played fine, so that seems to imply Code Generator isn't kicking in. Is there a better way to do this?
