Missing "provideAuth(() => getAuth())" in modular and advanced sample?

[RafOXxxx]

I tried to use the modular sample as a template and run into a NullInjectorError until I added provideAuth(() => getAuth()) to the imports array inside app.module.ts. That made me wonder how the provided samples are functional without it?

In the samples provideAuth() is called in the app.browser.module.ts. Most the reasons why I split those out should not be necessary as of Firebase JS SDK 9.1

Thanks for the reply, I totally disregarded that app.browser.module.ts.
