 * <p>Lists the MFA devices for an IAM user. If the request includes a IAM user name,
 *             then this operation lists all the MFA devices associated with the specified user. If you
 *             do not specify a user name, IAM determines the user name implicitly based on the Amazon Web Services
 *             access key ID signing the request for this operation.</p>

 * import { IAMClient, ListMFADevicesCommand } from "@aws-sdk/client-iam"; // ES Modules import
 * // const { IAMClient, ListMFADevicesCommand } = require("@aws-sdk/client-iam"); // CommonJS import
