/**
 * @module NamespacePicker
 * @description component is used to display a dropdown listing all namespaces that the current user has access to.
 *  The user can select a namespace from the dropdown to navigate directly to that namespace.
 *  The "Manage" button directs the user to the namespace management page.
 *  The "Refresh List" button refreshes the list of namespaces in the dropdown.

Review comment (suggestion):
there is a  `type Store from '@ember-data/store'`, that I see used elsewhere, would that work here? 
```suggestion
  @service declare store: Store;
```

Code after:
import { tracked } from '@glimmer/tracking';

import type Router from 'vault/router';
import type NamespaceService from 'vault/services/namespace';
import type AuthService from 'vault/vault/services/auth';
import type Store from '@ember-data/store';

interface NamespaceOption {
  id: string;
  path: string;
  label: string;
