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?
