/**
 * <p>This API allows you to connect WebRTC-enabled devices with Alexa display devices. When
 *             invoked, it sends the Alexa Session Description Protocol (SDP) offer to the master peer.
 *             The offer is delivered as soon as the master is connected to the specified signaling
 *             channel. This API returns the SDP answer from the connected master. If the master is not
 *             connected to the signaling channel, redelivery requests are made until the message
 *             expires.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { KinesisVideoSignalingClient, SendAlexaOfferToMasterCommand } from "@aws-sdk/client-kinesis-video-signaling"; // ES Modules import
 * // const { KinesisVideoSignalingClient, SendAlexaOfferToMasterCommand } = require("@aws-sdk/client-kinesis-video-signaling"); // CommonJS import
 * // import type { KinesisVideoSignalingClientConfig } from "@aws-sdk/client-kinesis-video-signaling";
 * const config = {}; // type is KinesisVideoSignalingClientConfig
 * const client = new KinesisVideoSignalingClient(config);
 * const input = { // SendAlexaOfferToMasterRequest
 *   ChannelARN: "STRING_VALUE", // required
 *   SenderClientId: "STRING_VALUE", // required
 *   MessagePayload: "STRING_VALUE", // required
 * };
 * const command = new SendAlexaOfferToMasterCommand(input);
 * const response = await client.send(command);
 * // { // SendAlexaOfferToMasterResponse
 * //   Answer: "STRING_VALUE",
 * // };
 *
 * ```
 *
 * @param SendAlexaOfferToMasterCommandInput - {@link SendAlexaOfferToMasterCommandInput}
 * @returns {@link SendAlexaOfferToMasterCommandOutput}
 * @see {@link SendAlexaOfferToMasterCommandInput} for command's `input` shape.
 * @see {@link SendAlexaOfferToMasterCommandOutput} for command's `response` shape.

 *
 * @throws {@link ClientLimitExceededException} (client fault)
 *  <p>Your request was throttled because you have exceeded the limit of allowed client
 *             calls. Try making the call later.</p>
