/**
 * <p>Returns details about the IAM user or role whose credentials are used to call the
 *             operation.</p>
 *         <note>
 *             <p>No permissions are required to perform this operation. If an administrator adds a
 *                 policy to your IAM user or role that explicitly denies access to the
 *                     <code>sts:GetCallerIdentity</code> action, you can still perform this operation.
 *                 Permissions are not required because the same information is returned when an IAM
 *                 user or role is denied access. To view an example response, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/troubleshoot_general.html#troubleshoot_general_access-denied-delete-mfa">I Am Not Authorized to Perform: iam:DeleteVirtualMFADevice</a> in the
 *                     <i>IAM User Guide</i>.</p>
 *         </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { STSClient, GetCallerIdentityCommand } from "@aws-sdk/client-sts"; // ES Modules import
 * // const { STSClient, GetCallerIdentityCommand } = require("@aws-sdk/client-sts"); // CommonJS import
 * const client = new STSClient(config);
 * const command = new GetCallerIdentityCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link GetCallerIdentityCommandInput} for command's `input` shape.
 * @see {@link GetCallerIdentityCommandOutput} for command's `response` shape.
 * @see {@link STSClientResolvedConfig | config} for command's `input` shape.
