Как воспользоваться методами маркера из библиотеки Ymaps?

Question

[2Ernest5]

Всем привет, использую компонент для Vue . Не понимаю как обращаться к методам маркера. Интересует метод getClosestPoint

<template>
  <yandex-map @click="setMarker" @map-was-initialized="mapInit" :coords="coords" :zoom="zoom">
    <ymapMarker
      ref="mkad"
      marker-id="1"
      marker-type="Polygon"
      :coords="mkadCoords"
    />
    <ymap-marker
      v-if="markerCoords"
      :coords="markerCoords"
      marker-id="marker"
      hint-content="some hint"
    />
  </yandex-map>
</template>

<script>
import { yandexMap, ymapMarker } from 'vue-yandex-maps';

export default {
