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.

检查 callable function 定义、app.module.ts、firebase.json 以及使用 httpsCallableData 的 Angular 组件，并将配置的 europe-west1 区域与已部署的生产环境进行比较。重现生产环境调用并追踪其返回 Unauthenticated 的原因；完成的标准是已部署的 V1 callable 能够从 Angular 应用中正常工作且不再出现该错误。
