TeamsUserCredential - Unable to get a token for a specific scope

[schnito]

Describe the bug
Calling TeamsUserCredential getToken with a scope as parameter generates the error "Error - Failed to get access token cache silently, please login first: you need login first before get access token.".
It works well if we specify empty string: getToken("")

To Reproduce
Steps to reproduce the behavior:

1. Create new Tab app with React
2. Follow the guide to configure SSO https://learn.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/authentication/tab-sso-overview
3. In Tab.tsx, add the following code to get a token
   const { teamsUserCredential } = useContext(TeamsFxContext);
   const { loading, data, error } = useData(async () => {
   if (teamsUserCredential) {
   const userInfo = await teamsUserCredential.getUserInfo();
   const token = await teamsUserCredential.getToken(["access_as_user"]);
   return token;
   }
   });
4. Run the application, login with your accont. Open developer console and see the error

Expected behavior
A token should by returned for a specific scope
