/**
 * <p>Describes the specified flow.</p>
 *          <p>You can also create and update flows using the <a href="https://docs.aws.amazon.com/connect/latest/APIReference/flow-language.html">Amazon Connect
 *    Flow language</a>.</p>
 *          <p>Use the <code>$SAVED</code> alias in the request to describe the <code>SAVED</code> content of a Flow. For
 *    example, <code>arn:aws:.../contact-flow/\{id\}:$SAVED</code>. After a flow is published, <code>$SAVED</code> needs to
 *    be supplied to view saved content that has not been published.</p>
 *          <p>Use <code>arn:aws:.../contact-flow/\{id\}:\{version\}</code> to retrieve the content of a specific flow
 *    version.</p>
 *          <p>In the response, <b>Status</b> indicates the flow status as either <code>SAVED</code>
 *    or <code>PUBLISHED</code>. The <code>PUBLISHED</code> status will initiate validation on the content.
 *     <code>SAVED</code> does not initiate validation of the content. <code>SAVED</code> | <code>PUBLISHED</code>
 *          </p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { ConnectClient, DescribeContactFlowCommand } from "@aws-sdk/client-connect"; // ES Modules import
 * // const { ConnectClient, DescribeContactFlowCommand } = require("@aws-sdk/client-connect"); // CommonJS import
 * // import type { ConnectClientConfig } from "@aws-sdk/client-connect";
 * const config = {}; // type is ConnectClientConfig
 * const client = new ConnectClient(config);
 * const input = { // DescribeContactFlowRequest
 *   InstanceId: "STRING_VALUE", // required
 *   ContactFlowId: "STRING_VALUE", // required
 * };
 * const command = new DescribeContactFlowCommand(input);
 * const response = await client.send(command);
 * // { // DescribeContactFlowResponse
 * //   ContactFlow: { // ContactFlow
 * //     Arn: "STRING_VALUE",
 * //     Id: "STRING_VALUE",

 * //     State: "ACTIVE" || "ARCHIVED",
 * //     Status: "PUBLISHED" || "SAVED",

 * //     Content: "STRING_VALUE",
 * //     Tags: { // TagMap

 * //     },
 * //     FlowContentSha256: "STRING_VALUE",
 * //     Version: Number("long"),
