Advanced geolocation problem in ionic v4 (angular)

Hi everyone. I’ve some problem with cordova-plugin-advanced-geolocation. I try to use them in project but had problem to initialize global variables (she not defined) to use plugin method.

import { Component } from '@angular/core';

import { Platform } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';
import { DataService } from './tab1/service/data.service';

declare let AdvancedGeolocation: any;

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.scss']
})
export class AppComponent {
  constructor(
      private platform: Platform,
      private splashScreen: SplashScreen,
      private statusBar: StatusBar,
      private dataService: DataService,
  ) {
    this.initializeApp();
  }

  initializeApp() {
    this.platform.ready().then(() => {
      this.statusBar.styleDefault();
      this.splashScreen.hide();

      if (this.platform.is('android')) {
        this.initGeo();
      } else {
        alert('wrong platform');
      }
    });
  }

  initGeo() {
    AdvancedGeolocation.start((success) => {
          try {

          } catch (e) {
            console.log(e);
          }
        },
        (err) => {
          console.log('ERROR! ' + JSON.stringify(err));
        },
