CloudAdapter don't work with Teams SSO

Versions

What package version of the SDK are you using. 4.19.0
What nodejs version are you using: 16.19.0
What browser version are you using: Teams Windows Client
What os are you using. Windows 10

Describe the bug

Teams SSO doesn't work with the CloudAdapter class. I spent a lot of time with debugging and checking my configuration.
I followed the instructions at this repo: https://github.com/OfficeDev/Microsoft-Teams-Samples/tree/main/samples/bot-conversation-sso-quickstart/js

After sending the OAuthPromt Dialog, I get an error message "ExtendedUserTokenProvider".
If I use the deprecated BotFrameworkAdapter everything works as expected.

This happens because the CloudAdapter doesn't implement the "exchangeToken" method (i guess).
So I'm not sure whether the samples or the lib is not as expected.

To Reproduce

Use the code and instructions from: https://github.com/OfficeDev/Microsoft-Teams-Samples/tree/main/samples/bot-conversation-sso-quickstart/js

Expected behavior

Teams SSO with the CloudAdapter class.

Hi @johnataylor. We were able to reproduce this issue using the bot-conversation-sso-quickstart sample.
If there's no problem, we could continue reviewing it.
