/**
 * <p>Initiates a connection to a target (for example, an instance) for a Session Manager session. Returns a
 *    URL and token that can be used to open a WebSocket connection for sending input and receiving
 *    outputs.</p>
 *          <note>
 *             <p>Amazon Web Services CLI usage: <code>start-session</code> is an interactive command that requires the Session Manager
 *     plugin to be installed on the client machine making the call. For information, see <a href="https://docs.aws.amazon.com/systems-manager/latest/userguide/session-manager-working-with-install-plugin.html">Install
 *      the Session Manager plugin for the Amazon Web Services CLI</a> in the <i>Amazon Web Services Systems Manager User Guide</i>.</p>
 *             <p>Amazon Web Services Tools for PowerShell usage: Start-SSMSession isn't currently supported by Amazon Web Services Tools
 *     for PowerShell on Windows local machines.</p>

 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { SSMClient, StartSessionCommand } from "@aws-sdk/client-ssm"; // ES Modules import
 * // const { SSMClient, StartSessionCommand } = require("@aws-sdk/client-ssm"); // CommonJS import
 * const client = new SSMClient(config);
 * const command = new StartSessionCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link StartSessionCommandInput} for command's `input` shape.
 * @see {@link StartSessionCommandOutput} for command's `response` shape.
 * @see {@link SSMClientResolvedConfig | config} for command's `input` shape.
