Slug Field does not conver the string into a Slug

[KasparRosin]

Laravel: 11
Nova: 5

Slug::make('Slug')
  ->separator('-')
  ->rules('required', 'max:255')
  ->creationRules('unique:products,slug')
  ->updateRules('unique:products,slug,{{resourceId}}')
  ->hideFromIndex(),

Based on the documentation:

By default, the field will convert a string like ‘My Blog Post’ to a slug like ‘my-blog-post’. If you would like the field to use underscores instead of dashes, you may use the separator method to define your own custom “separator”:

Reality is, that it does not?
I can't really tell if the slugifying only works if you define from attribute?
