//
// # Library status
//
// These client libraries are officially supported by Google. However, this
// library is considered complete and is in maintenance mode. This means
// that we will address critical bugs and security issues but will not add
// any new features.
//
// When possible, we recommend using our newer
// [Cloud Client Libraries for Go](https://pkg.go.dev/cloud.google.com/go)
// that are still actively being worked and iterated on.
//
// # Creating a client
//
// Usage example:
//
//	import "google.golang.org/api/sts/v1beta"
//	...
//	ctx := context.Background()
//	stsService, err := sts.NewService(ctx)
//
// In this example, Google Application Default Credentials are used for
// authentication. For information on how to create and obtain Application
// Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.
//
// # Other authentication options
//
// To use an API key for authentication (note: some APIs do not support API
// keys), use [google.golang.org/api/option.WithAPIKey]:
//
//	stsService, err := sts.NewService(ctx, option.WithAPIKey("AIza..."))
//
// To use an OAuth token (e.g., a user token obtained via a three-legged OAuth
// flow, use [google.golang.org/api/option.WithTokenSource]:
//
//	config := &oauth2.Config{...}
//	// ...
//	token, err := config.Exchange(ctx, ...)
//	stsService, err := sts.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
//
// See [google.golang.org/api/option.ClientOption] for details on options.

	// Regional endpoints are also supported. - `method`: The HTTP request method:

	// `Authorization`: The request signature. - `x-amz-date`: The time you will
	// send the request, formatted as an ISO8601 Basic
	// (https://docs.aws.amazon.com/general/latest/gr/sigv4_elements.html#sigv4_elements_date)

	// { "headers": [ {"key": "x-amz-date", "value": "20200815T015049Z"}, {"key":
	// "Authorization", "value":
	// "AWS4-HMAC-SHA256+Credential=$credential,+SignedHeaders=host;x-amz-date;x-goo

	// "https://sts.amazonaws.com?Action=GetCallerIdentity&Version=2011-06-15" }

	// to obtain an access token with new security attributes applied, such as a
	// Credential Access Boundary. In this case, set `subject_token_type` to
