The list of JWT
[audiences](https://tools.ietf.org/html/draft-ietf-oauth-json-web-token-32#section-4.1.3).
that are allowed to access. A JWT containing any of these audiences will
be accepted. When this setting is absent, only JWTs with audience
"https://[Service_name][google.api.Service.name]/[API_name][google.protobuf.Api.name]"
will be accepted. For example, if no audiences are in the setting,
LibraryService API will only accept JWTs with the following audience
"https://library-example.googleapis.com/google.example.library.v1.LibraryService".
Example:
audiences: bookstore_android.apps.googleusercontent.com,
bookstore_web.apps.googleusercontent.com
