The Virto Alerts application requires both **Delegated** and **Application** permissions.

## Delegated Permissions

Delegated permissions are used to authorize users and manage frontend functionalities such as alerts.

## Application Permissions

Application permissions are used for background services. Specifically, they are required for:

1. **Handling List Changes and Generating Emails**: This involves reading users, groups, and SharePoint list items based on alert configurations.
2. **Updating List Webhook Subscriptions**: To receive notifications of list changes, the application requires permissions similar to "List.Manage." However, since this specific permission is not available via the API, "Sites.Manage.All" is requested instead.
