Hi @Suraj Dengale
This error means that your app is missing one of the Chat.ReadBasic
, Chat.Read
and Chat.ReadWrite
permissions, please ensure that your user or admin has dynamically consented to these permissions when logged in, or click "Grant admin consent for xxxxxx" button to grant admin consent.
You can use jwt.ms to decode your access token and check the scp
claim to see the list of permissions the current token has.
Hope this helps.
