- **Package Name**: azure-communication-chat
- **Package Version**: 1.3.0
- **Operating System**: Windows 11 Enterprise
- **Python Version**: 3.9.11

**Describe the bug**
I am building a web application where I create a chat thread using ACS SDK and looking to enable communication between ACS user and Microsoft team's user, currently when trying to add Microsoft teams users to the chat thread I am facing the following error:

**Error**

Traceback (most recent call last):

```

**Additional context**

I am trying to replicate this behavior as mentioned in [Q&A](https://learn.microsoft.com/en-us/answers/questions/1655403/how-can-i-enable-chat-communication-between-extern) is it possible to bridge a chat solution between ACS user and Teams user without creating a [meeting link](https://learn.microsoft.com/en-us/azure/communication-services/quickstarts/chat/meeting-interop?pivots=platform-web) ?
