How to center and scale the map in Yandex maps after laying the route so that the entire route fits in the visible area?

Question

Yandex maps

Hello!
You have the following code on the page, which creates a map centered on City1, then routes between City1 and City2, and you want to. so that after the route is laid, fit the entire route in the visible area of ​​the map.

ymaps.ready(init);

function init() {
  ymaps.geocode('Москва', { results: 1 }).then(function(res){
    var city = res.geoObjects.get(0);
    
    var myMap = new ymaps.Map("route-map", {
          center: city.geometry.getCoordinates(),
          zoom: 4
     });
    
    ymaps.route(['Москва','Самара']).then(function (route) {
      myMap.geoObjects.add(route);
      var points = route.getWayPoints(),
        lastPoint = points.getLength() - 1;
      points.options.set('preset', 'twirl#redStretchyIcon');
      points.get(0).properties.set('iconContent', 'A');
      points.get(lastPoint).properties.set('iconContent', 'B');

    }, function (error) {
      alert('Возникла ошибка: ' + error.message);
    });
  });
}

Tried calling the following functions:

myMap.setBounds(route.getBounds(), { margin: 50, checkZoomRange: true });
myMap.setZoom(myMap.getZoom());

But nothing has changed, the center of the map remains at the City1 point, and if the route is long enough, then the end point of City2 is outside the visibility area.
