how to Initialize the config dynamically?

I'm looking for a simple way to `initializeApp` later inside of the `app.component.ts` NOT in my `app.config.ts`. I need to do this because of my current app implementation and requirements...

Currently, here's my `app.config.ts` file:
```ts
import { provideFirebaseApp, initializeApp } from '@angular/fire/app';
import { getAnalytics, provideAnalytics } from '@angular/fire/analytics';

export const appConfig: ApplicationConfig = {
providers: [
provideFirebaseApp(() =>
initializeApp({
apiKey: 'xxx',
authDomain: 'xxx.firebaseapp.com',
databaseURL: 'https://xxx.firebaseio.com',
projectId: 'xxx',
storageBucket: 'xxx',
messagingSenderId: '123',
appId: 'xxx',
measurementId: 'xxx',
}),
),
provideAnalytics(() => getAnalytics()),
...
],
...
})
```

Any help is so appreciated ❤️

### Version info

**Angular:** 17.3.3

**Firebase:** ^10.13.1

**AngularFire:** ^18.0.1

Start by comparing the current app.config.ts setup with the requested initialization point in app.component.ts, focusing on provideFirebaseApp, initializeApp, provideAnalytics, and getAnalytics. Determine whether the existing entry points support deferred configuration and define a reproducible Angular 17/Firebase 10 behavior that confirms the configuration is initialized later.
