How to get status code in angular observable

I have services below that I'd like to get status code and handle if statements in it but so far I couldn't figure it out

import { Injectable } from '@angular/core';
import { EnvService } from './env.service';
import { tap } from 'rxjs/operators';
import { Observable, from } from 'rxjs';
import { map, switchMap } from 'rxjs/operators';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { NativeStorage } from '@ionic-native/native-storage/ngx';
import { Plugins } from '@capacitor/core';
const { Storage } = Plugins;

@Injectable({
providedIn: 'root'
})
export class InvoicesServiceService {

token: any;

constructor(
private env: EnvService,
private http: HttpClient,
private nativeStorage: NativeStorage
) {
Storage.get({ key: 'token' }).then((token: any) => {
this.token = JSON.parse(token.value)
}).catch(error => console.error(error));
}

// All
getInvoices(): Observable<any> {
const tokenPromise =
this.token === undefined
? Storage.get({ key: 'token' })
: Promise.resolve(this.token);

return from(tokenPromise).pipe(
switchMap((token) => {
this.token = this.token;
const httpOptions = {
headers: new HttpHeaders({
Accept: 'application/json, text/plain',
'Content-Type': 'application/json',
Authorization: this.token.access_token,
}),
};
return this.http
.get(`${this.env.Dashboard}` + '/invoices', httpOptions)
.pipe(map((data) => data));
})
);
}


What I try to do is that if, status code is 403 redirect user to specific route other than that just return data.

any idea?
