401 - Unauthorised Error while accessing Graph API for MS Teams beta version

Question

Hello,

I'm trying to access message of Particular group in MS Teams using Graph API.

I'm using below URL to get Teams messages.

https://graph.microsoft.com/beta/teams/{group-id-for-teams}/channels/{channel-id}/messages

I have passed correct token generated using below URL.

https://login.microsoftonline.com/{Tenent Id}/oauth2/v2.0/token

I'm facing 401 - Unauthorised error while accessing message.

I'm able to access SharePoint Graph APIs using same access_token but can't access beta Version APIs.

Is there any solution for such situation??
