 * <p>Retrieves a direct assignment of a user or group to an application. If the user doesn’t have a direct assignment to the application, the user may still have access to the application through a group. Therefore, don’t use this API to test access to an application for a user. Instead use <a>ListApplicationAssignmentsForPrincipal</a>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript

 * // const { SSOAdminClient, DescribeApplicationAssignmentCommand } = require("@aws-sdk/client-sso-admin"); // CommonJS import
 * // import type { SSOAdminClientConfig } from "@aws-sdk/client-sso-admin";
 * const config = {}; // type is SSOAdminClientConfig
 * const client = new SSOAdminClient(config);
 * const input = { // DescribeApplicationAssignmentRequest
 *   ApplicationArn: "STRING_VALUE", // required
 *   PrincipalId: "STRING_VALUE", // required
 *   PrincipalType: "USER" || "GROUP", // required
 * };
 * const command = new DescribeApplicationAssignmentCommand(input);
 * const response = await client.send(command);
 * // { // DescribeApplicationAssignmentResponse
