/**
 * <p>Creates a custom timeline event on the incident details page of an incident record.
 *       Incident Manager automatically creates timeline events that mark key moments during an incident.
 *       You can create custom timeline events to mark important events that Incident Manager can detect
 *       automatically.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { SSMIncidentsClient, CreateTimelineEventCommand } from "@aws-sdk/client-ssm-incidents"; // ES Modules import
 * // const { SSMIncidentsClient, CreateTimelineEventCommand } = require("@aws-sdk/client-ssm-incidents"); // CommonJS import
 * // import type { SSMIncidentsClientConfig } from "@aws-sdk/client-ssm-incidents";
 * const config = {}; // type is SSMIncidentsClientConfig
 * const client = new SSMIncidentsClient(config);
 * const input = { // CreateTimelineEventInput
 *   clientToken: "STRING_VALUE",
 *   incidentRecordArn: "STRING_VALUE", // required
 *   eventTime: new Date("TIMESTAMP"), // required
 *   eventType: "STRING_VALUE", // required
 *   eventData: "STRING_VALUE", // required
 *   eventReferences: [ // EventReferenceList
 *     { // EventReference Union: only one key present
 *       resource: "STRING_VALUE",
 *       relatedItemId: "STRING_VALUE",
 *     },
 *   ],
 * };
 * const command = new CreateTimelineEventCommand(input);
 * const response = await client.send(command);
