Nova Pivot BelongsToMany not working in table

I have the following Pivot table:

public function sheeps()
{
    return $this->belongsToMany(Sheep::class, 'farm_sheep')->withTimestamps()->withPivot(['weight', 'foobar']);
}

Now I want a BelongsToMany field that shows the values that are in the pivot Table, so: weight and foobar. But when I do that, it just shows the table with the data from the Sheep Nova resource. So not that pivot tables values. What am I doing wrong

BelongsToMany::make('Sheeps')
    ->fields(function () {
        return [
            Number::make('Weight'),
            Textarea::make('Foobar'),
        ];
    }),
