How can I add alpine plugin to my filament plugin?

import sort from '@alpinejs/sort'
document.addEventListener('alpine:init', () => {
    window.Alpine.plugin(sort)
})

export default function widgetList({ options }) {
    return {

    };
}

<x-filament-widgets::widget>
    <x-filament::section>
        <div
            x-ignore
            ax-load
            ax-load-src="{{ \Filament\Support\Facades\FilamentAsset::getAlpineComponentSrc('widget-list', 'thethunderturner/widget-list') }}"
            x-data="widgetList({
                    options: @js($options),
                })">
            <ul x-sort>
                <li x-sort:item>foo</li>
                <li x-sort:item>bar</li>
                <li x-sort:item>baz</li>
            </ul>
        </div>
    </x-filament::section>
</x-filament-widgets::widget>
