Vue-apexcharts toolbar : selection tool not working - vue.js

Question

I created a line graph with vue apexcharts and I'm trying to enable the selection tool in the toolbar (as explain here :https://apexcharts.com/docs/options/chart/toolbar/ )
But even if I set :
selection: true,
It doesn't appear on the graph.
Here is my vue component :
<template>
<div class="container">
<apexchart :type="typechart" height="350" :options="options" :series="series"></apexchart>
</div>
</template>
<script lang="ts">
import { Vue, Component } from "vue-property-decorator";
import VueApexCharts from "vue-apexcharts";
Vue.component("apexchart", VueApexCharts);
#Component({
components: { MyPlot }
})
export default class MyPlot extends Vue {
witdhgraph: string = "500";
typechart: string = "line";

You also need to enable
chart: {
selection: {
enabled: true
}
}
This was not mentioned in the docs which have been corrected now: https://apexcharts.com/docs/options/chart/toolbar/#selection
