How to config a storybook for a ui library for Ionic & Angular

[manzapanza]

Hi!
I'm developing a library with some ui components for Ionic, and I would like to configure my first storybook to develop and document the library.
My lib doesn't have an AppController, but has only a module with a button component.

Here my stories file:

export default {
  title: 'AlertButtonComponent',
};

export const primary = () => ({
  moduleMetadata: {
    declarations: [AlertButtonComponent],
    imports: [IonicModule.forRoot()],
  },
  component: AlertButtonComponent,
  props: {
    label: text('label', 'Button Label'),
    message: text('message', 'Alert message!'),
  },
});

In the storybook the button works, but the style is not 100% like when is placed inside an Ionic app. I saw that on a normal app, Ionic apply some base css rules to the body tag, but how can achieve that?
Probably I need something like a parent App container to my button component, but how can I do that if I'm developing only a library?

Thank you in advance!
