Azure Communication Service - While creating ChatThreadClient, getting error 401

[salujamanish]

Hi Team,

I am following https://github.com/Azure/azure-docs-sdk-java/blob/master/docs-ref-services/communication-chat-readme-pre.md to setup chat client for azure communication service using Java Sdk.

I am able to get valid user access token but when I am trying to create chat thread using
ChatThreadClient chatThreadClient = chatClient.createChatThread(createChatThreadOptions);

I am getting below exception

Exception in thread "main" com.azure.communication.chat.models.ErrorException: Status code 401, (empty body)
