Documentation Request

Reproduction:

I wanted to auth with Google via Vercel. I looked up google-auth-library-node which had a deprecation notice and a link to google-cloud-node-core, which itself had a deprecation notice, and a link to this library, google-cloud-node.

I scrolled down to the auth section, and it links back to google-auth-library-node.

and repeat!

Expectation:

It would be good to understand what the official, non-deprecated way to auth to google cloud in 2026 is?
