Code review comment: I think I am not able to communicate my thought clearly  , and as I mentioned previously I am not saying clientId is a replacement of machineId, but thats fine , I can take this change later

Code under review:
public void init(CosmosClientMetadataCachesSnapshot metadataCachesSnapshot, Function<HttpClient, HttpClient> httpClientInterceptor) {
        try {
            
            

            this.httpClientInterceptor = httpClientInterceptor;
            if (httpClientInterceptor != null) {
                this.reactorHttpClient = httpClientInterceptor.apply(httpClient());
            }

            this.gatewayProxy = createRxGatewayProxy(this.sessionContainer,
                this.consistencyLevel,
                this.queryCompatibilityMode,
                this.userAgentContainer,
                this.globalEndpointManager,
                this.reactorHttpClient,
                this.apiType);
            this.globalEndpointManager.init();
            this.initializeGatewayConfigurationReader();

            if (metadataCachesSnapshot != null) {
                this.collectionCache = new RxClientCollectionCache(this,
                    this.sessionContainer,
                    this.gatewayProxy,
                    this,
                    this.retryPolicy,
                    metadataCachesSnapshot.getCollectionInfoByNameCache(),
                    metadataCachesSnapshot.getCollectionInfoByIdCache()
                );
            } else {
                this.collectionCache = new RxClientCollectionCache(this,
                    this.sessionContainer,
                    this.gatewayProxy,
                    this,
                    this.retryPolicy);
            }
            this.resetSessionTokenRetryPolicy = new ResetSessionTokenRetryPolicyFactory(this.sessionContainer, this.collectionCache, this.retryPolicy);

            this.partitionKeyRangeCache = new RxPartitionKeyRangeCache(RxDocumentClientImpl.this,
                collectionCache);

            updateGatewayProxy();
            clientTelemetry = new ClientTelemetry(this, null, UUID.randomUUID().toString(),
                ManagementFactory.getRuntimeMXBean().getName(), userAgentContainer.getUserAgent(),
                connectionPolicy.getConnectionMode(), globalEndpointManager.getLatestDatabaseAccount().getId(),
                null, null, this.reactorHttpClient, connectionPolicy.isClientTelemetryEnabled(), this, this.connectionPolicy.getPreferredRegions());
            clientTelemetry.init();
            if (this.connectionPolicy.getConnectionMode() == ConnectionMode.GATEWAY) {
                this.storeModel = this.gatewayProxy;
            } else {
                this.initializeDirectConnectivity();
            }
            this.retryPolicy.setRxCollectionCache(this.collectionCache);
        } catch (Exception e) {
            logger.error("unexpected failure in initializing client.", e);
            close();
            throw e;
        }
    }

Line commented on: clientTelemetry = new ClientTelemetry(this, null, UUID.randomUUID().toString(),
