I have the exactly code below, it's like equal to the documentation that it's presented in vueSax when importing individual components, but it does not seems to work. In my console it's printed this error: TypeError: Cannot read properties of undefined (reading 'install')

I'm currently using Vue 2 and vuesax 4.0.1-alpha.25

<template>
  <div class="playgrond2">
    <vs-button>test</vs-button>
  </div>
</template>

<script>
import Vue from "vue";
import { vsButton } from "vuesax";
import "vuesax/dist/vuesax.css";
Vue.use(vsButton);
export default {
  name: "Playground2",
};
</script>
