ClientAuthError in manage-teams-identity-mobile-and-desktop

I want to call with an ACS resource related to my Microsoft Teams user (add-1-on-1-cte-video-calling). So to get the right ACS token, I wanted to get mine with the tool: manage-teams-identity-mobile-and-desktop

All environment variables are set, and it runs on the URL http://localhost:3000
http://localhost:3000/redirect is set on the Azure portal as a Single page application redirect URL for my Teams BOT.
So everything should be okay, but when I run this, after login my Teams User the callback URL called back, but not with the AccessToken, but this error
```
{"errorCode":"network_error","errorMessage":"Network request failed. Please check network trace to determine root cause. | Fetch client threw: Error: HTTP status code 400 | Attempted to reach: https://login.microsoftonline.com/[MY_TENANT_ID_HIDDEN]/oauth2/v2.0/token","subError":"","name":"ClientAuthError"}
```
Teams Bot has all the necessary permissions.
