Non Node.js support - creating a wholly local Google Cloud API calling dashboard in the browser

### A screenshot that you have tested with "Try this API".

What do you think of this idea?

I can probably implement it by generating a new client library from your discovery JSON; or maybe hacking around a patch for this Node.js one and auto-applying it everytime you release.

### What would you like to see in the library?

0. Usable in the web browser, with no API server or anything like that (i.e., just serve some HTML+JS files off a CDN; keep auth tokens, region & other preferences, and dashboard customisations in LocalStorage)

### Describe alternatives you've considered

Writing a new library by hand.

Or generating a new library using your Discovery API https://cloud.google.com/docs/discovery/use-api
(e.g., by writing a tool to translate this to OpenAPI; then using one of the many OpenAPI generators to create nice JavaScript or TypeScript code)
