Я пытаюсь добавить службу направления на карту 1: мне нужно отобразить карту 2: как только я получу ответ от сервера или вызову метод, только тогда я должен нарисовать полилинию, которую я пытаюсь сделать, как показано ниже

В приведенном выше коде метод initMap будет рисовать простую карту, как только я вызову метод drawPolyline, он должен показать график (это потому, что я получу данные из zmq, как только я получу данные, которые я должен построить)
Я долго пытался это сделать, пожалуйста, помогите, опубликовав правильный код для этого, или предложите способ сделать это.
