Option to generate 3rd party chart types in vue2

[DRoet]

I assumed the code below would work for 3rd party charts, but generateChart() is not exposed inside vue-chartjs/legacy

Expected Behavior

<script>
import { generateChart } from 'vue-chartjs/legacy'
import { WordCloudController } from 'chartjs-chart-wordcloud'

components: {
   WordCloud: generateChart('WordCloud', 'wordCloud', WordCloudController),
},
</script>

Actual Behavior

import { generateChart } from 'vue-chartjs/legacy'
                 ^---- generateChart not exposed

Environment

• vue.js version: 2.6.x
• vue-chart.js version: 4.0.1
• chart.js version: 3.x
• npm version: 8.x
