react-native-background-geolocation: Heartbeat event doesn't getting called in case of stationary location when app is killed.

Your Environment

• Plugin version: react-native-background-geolocation": “3.9.3” & react-native-background-fetch": “3.0.6”
• Platform: iOS and android
• OS version: 13.5
• Device manufacturer / model: iPhone SE (2nd gen)
• React Native version (react-native -v): 0.62.2
• Plugin config

export const configureBackgroundGeoLocation = () => {
  BackgroundGeolocation.ready(
    {
      desiredAccuracy: BackgroundGeolocation.DESIRED_ACCURACY_HIGH,
      distanceFilter: stores.locationStore.fetchRadius || 10, //distance required for getting location update        // Activity Recognition
      stopTimeout: 1,
      // Application config
      debug: false, // <-- enable this hear sounds for background-geolocation life-cycle.
      logLevel: BackgroundGeolocation.LOG_LEVEL_VERBOSE,
      stopOnTerminate: false, // <-- Allow the background-service to continue tracking when user closes the app.
      startOnBoot: true, // <-- Auto start tracking when device is powered-up.
      locationAuthorizationRequest: 'Always',
      heartbeatInterval: 60,
      preventSuspend: true, //required for heartbeat event for ios,
      foregroundService: true,
    },
    state => {
      LOGGER.log(
        '- BackgroundGeolocation is configured and ready: ',
        state.enabled,
      );

      if (!state.enabled) {
        BackgroundGeolocation.start(function() {
          LOGGER.log('- Start success');
        });
      }
    },
  );

BackgroundGeolocation.on('location', location => {
    console.log('On location:', location);
    location && getLocationInputAndSave(location);
  });

  /**
   * this will get called whenever it has been elapsed 1 min and device is sationary i.e there is no change in location from last 1min
   */
  BackgroundGeolocation.onHeartbeat(event => {
    // You could request a new location if you wish.

    BackgroundGeolocation.getCurrentPosition({
      samples: 1,
      persist: true,
    }).then(location => {
      console.log('On heartbeat:', location);
      // location && getLocationInputAndSave(location);
    });
  });

Expected Behavior

We should get stationary data by calling the heartbeat event even if the app is killed.

Actual Behavior

We are not getting stationary data when the app is killed although we are getting it when the app is in foreground or background state.
