A plugin must either be a function or an object with an "install" function

Describe the bug I am not able to install the plugin. I receive a warning on the vue console in my browser. [Vue warn]: A plugin must either be a function or an object with an "install" function.

To Reproduce

This is my main.js

import { createApp } from 'vue';
import { createRouter, createWebHistory } from 'vue-router';

import { ActionCableVue } from 'actioncable-vue';

import App from './App.vue';
import GameComponent from './components/GameComponent.vue';
import HomeComponent from './components/HomeComponent.vue';

const app = createApp(App)
const routes = [
  { path: '/home', component: HomeComponent },
  { path: '/game', component: GameComponent }
]

const router = createRouter({
  mode: 'history',
  history: createWebHistory(),
  routes: routes
})

app.use(router)

app.use(ActionCableVue, {
  debug: true,
  debugLevel: 'error',
  connectionUrl: 'ws://localhost:3000/api/cable',
  connectImmediately: true,
})

app.mount('#app')

Expected behaviour I would expect that $cable is ready to use in my components.

Screenshots

This is a screenshot from the browser console

These are my used packages which includes the vue version

Plugin version: 2.3.2

Additional context I am new to vue and I am using the newest version of vue 3.0.0. The project is started fresh.

@DenniJensen This plugin currently only supports Vue 2.0. I’ll look into adding Vue 3.0 support as soon as I can.

@docming @DenniJensen @timmaier Vue 3 support just went live thanks to #37. Kindly update to actioncable-vue 2.4.0.
