First, you need to buy a license here: https://spatie.be/index.php/docs/laravel-comments/v1/getting-a-license

Then follow the steps here: https://spatie.be/index.php/docs/laravel-comments/v1/installation-setup

You also have to install the livewire components library: https://spatie.be/index.php/docs/laravel-comments/v1/livewire-components/installation

Then in your AppServiceProvider's boot method, include these two:

Filament::registerRenderHook(
    'head.end',
    fn (): string => Blade::render('<x-comments::styles />'),
);
 
Filament::registerRenderHook(
    'body.end',
    fn (): string => Blade::render('<x-comments::scripts />'),
);

Then create a Widget for the Resource where you want to use the comments, for example, DeliveryResource.

php artisan make:filament-widget Comments --resource=DeliveryResource

Then add public ?Model $record = null; to the Widget Resource you created.

Edit the Widget's view file:

<x-filament::widget>
    <x-filament::card>
        <livewire:comments :model="$record" />
    </x-filament::card>
</x-filament::widget>

Include the Widget in the Resource:

public static function getWidgets(): array
{
    return [
        Comments::class,
    ];
}

And also include in the EditPage:

protected function getFooterWidgets(): array
{
    return [
        DeliveryResource\Widgets\Comments::class,
    ];
}

You are done!
