How can I block cookies for beeing stored in the browser in Angular?

问题

I'm currently building a little angular page. In this page I'm using ngx-cookieconsent (https://www.npmjs.com/package/ngx-cookieconsent) for handling the cookies.

Everything works but now I'm a little bit confused. I've set it up with the parameter opt-in but when I visit the page first, there are already cookies stored in the browser even if I press decline or nothing:

Thats really confusing. I've also tried subscribing to the status change of the consent:

this.statusChangeSubscription = this.ccService.statusChange$.subscribe(
  (event: NgcStatusChangeEvent) => {
    console.log('Changed');
  });

But I still don't know why there are cookies before and how I can block them again if the user presses the decline button.

Does anyone can explain this please?
