How can i update components slots

I have fresh install on drupal cms.

I found theme header component.
web/themes/contrib/byte_theme/components/navbar/navbar.component.yml

I add three slots:

```slots:
  logo:
    title: Site logo
  navigation:
    title: Navigation menu
  links:
    title: CTAs
  links2:
    title: CTAs2
  example:
    title: Example

```

I can see them on my canvas edit. but when i change in CTAs i can see change in title.

So my question is how can i update slots to be visible on canvas, and where this component is added, so i can add new component to be visible on canvas as default block on every page.
