Callable functions with custom region not working, Unauthenticated error

### Version info

**Angular:**
15.2.2

**Firebase:**
9.23.0

**AngularFire:**
7.6.1

### How to reproduce these conditions

**Steps to set up and reproduce**

1. Create angular 15 project
2. Add angularfire
3. Create callable functions with custom region

### Debug output

** Errors in the JavaScript console **

```
main.fc6d01fc3332ae31.js:1 ERROR Error: Uncaught (in promise): Error: FirebaseError: Unauthenticated
Error: FirebaseError: Unauthenticated
```

** Output from `firebase.database().enableLogging(true);` **

How/where do I enable this?

Callable function:

```
import { region } from 'firebase-functions';

export const getInvoicesPerQuarter= region('europe-west1')
.https.onCall(async (data: { id: string; invoiceNumber: string }, context) => {
...
})
```

app.module.ts:

```
provideFunctions(() => {
const functions = getFunctions(getApp(), 'europe-west1');
// const functions = getFunctions();
if (environment.useEmulators) {
connectFunctionsEmulator(functions, 'localhost', 5001);
}
return functions;
}),
```

firebase.json:

```
{
"hosting": [
{
"rewrites": [
{
"source": "/getInvoicesPerQuarter",
"function": "getInvoicesPerQuarter"
}
]
},

```
angular component:

```
import { Functions, httpsCallableData } from '@angular/fire/functions';

const getInvoicesPerQuarterCallable: (data: {
year: number;
quarter: number;
}) => Observable = httpsCallableData<
{ year: number; quarter: number },
string
>(this.functions, 'getInvoicesPerQuarter');

const result = await firstValueFrom(
getInvoicesPerQuarterCallable({ year, quarter }),
);
```

Calling this callable function works in the emulator.
I deploy this to firebase.
I doesn't work on production and I get the Unauthenticated error.
I already contacted firebase support but everything looks fine and they say it's an AngularFire issue and can't help me.
Functions are V1.

Revisa la definición de la función invocable, app.module.ts, firebase.json y el componente de Angular que usa httpsCallableData, comparando la región configurada europe-west1 con la configuración de producción desplegada. Reproduce la llamada de producción y rastrea por qué devuelve Unauthenticated; el trabajo estará terminado cuando la función invocable V1 desplegada funcione desde la aplicación Angular sin ese error.
