My firebase app has a prod and a test environment. I would like to lock down the test environment completely to folks outside of my GSuite domain, so unauthorized folks can't see the app at all.
In appengine land, this is really straightforward using Cloud IAP (Identity-aware proxy). Is there an equivalent in the firebase world?
I know this maybe sounds redundant w/firebase auth, but I don't want randoms to even be able to load the page, and I also don't want to mess with the firebase auth config (which has its own rules, and multiple service providers etc that I'd prefer not to change for the test env).
