 This service is responsible for authenticating users to Azure Communication Services. Users of your Communication Services applications will require an `Access Token` in order to participate in chat threads and VoIP calls. The Azure Function will work as a trusted middleman between the user and the Communication Services. This allows you to provision access tokens without exposing your resource connection string to your users.
