If the app is initialized, can I use the client library or methods without initializing fbClient?

[lazyweb3]

I've to add Google/Github login and I've the app working fine with fbAdmin but I wish to know can I use fbClient library as well so that I can use getAuth, getStorage, etc?

My app's auth is getting initialised but as soon as I import getAuth() and use this, I get this error.

Unhandled Runtime Error
FirebaseError: Firebase: Need to provide options, when not being deployed to hosting via source. (app/no-options).
