Shown when required apps declared in `manifest.dependencies` are not installed or enabled. CnAppRoot mounts this automatically; apps can override the `#dependency-missing` slot for custom branding.

Not installed:

```vue
<div style="height: 320px; background: var(--color-main-background); border: 1px solid var(--color-border); border-radius: 8px; overflow: hidden;">
  <CnDependencyMissing
    :dependencies="[
      { id: 'openregister', name: 'Open Register' },
      { id: 'opencatalogi', name: 'Open Catalogi' },
    ]"
    heading="Missing dependencies"
    intro="The following apps must be installed before you can use this application." />
</div>
```

App installed but disabled:

```vue
<div style="height: 280px; background: var(--color-main-background); border: 1px solid var(--color-border); border-radius: 8px; overflow: hidden;">
  <CnDependencyMissing
    :dependencies="[
      { id: 'openregister', name: 'Open Register', enabled: false },
    ]"
    heading="App disabled"
    intro="Enable the following app to continue." />
</div>
```

With appName and custom link labels:

```vue
<div style="height: 280px; background: var(--color-main-background); border: 1px solid var(--color-border); border-radius: 8px; overflow: hidden;">
  <CnDependencyMissing
    app-name="My App"
    :dependencies="[
      { id: 'openregister', name: 'Open Register' },
      { id: 'spreed', name: 'Nextcloud Talk', enabled: false },
    ]"
    install-label="Install now"
    enable-label="Enable now" />
</div>
```

## Additional props

| Prop | Type | Default | Description |
|------|------|---------|-------------|
| `appName` | String | `''` | Optional name of the host app included in the default heading |
| `installLabel` | String | `'Install and enable'` | Label shown on the action for apps that are not yet installed |
| `enableLabel` | String | `'Enable'` | Label shown on the action for apps that are installed but disabled |
| `askAdminLabel` | String | `'Ask your administrator to enable {name}'` | Non-admin copy shown in place of the action; `{name}` is replaced by the dependency's display name |

For an admin (`getCurrentUser().isAdmin`) each dependency renders an install/enable button driven by [`useAppInstaller`](../../../docs/utilities/composables/use-app-installer.md) — one click installs-and-enables the app via Nextcloud's `settings/apps/enable` endpoint and reloads on success; on failure the error shows inline and the store link stays as a fallback. Non-admins see the `askAdminLabel` copy instead.
