// Retrieves the specified inline policy document that is embedded in the
// specified IAM user.
//
// Policies returned by this operation are URL-encoded compliant with [RFC 3986]. You can
// use a URL decoding method to convert the policy back to plain JSON text. For
// example, if you use Java, you can use the decode method of the
// java.net.URLDecoder utility class in the Java SDK. Other languages and SDKs
// provide similar functionality, and some SDKs do this decoding automatically.
//
// An IAM user can also have managed policies attached to it. To retrieve a
// managed policy document that is attached to a user, use [GetPolicy]to determine the
// policy's default version. Then use [GetPolicyVersion]to retrieve the policy document.
//
// For more information about policies, see [Managed policies and inline policies] in the IAM User Guide.
