Yes, that's correct. If the Azure AD token being used has the necessary permissions to access the Delta tables, then you don't need any additional management token. However, if the Azure AD token does not have the necessary permissions, you would need to authenticate using a personal access token (PAT) that has the required permissions.

Additionally, when using the Azure AD token, the token lifetime is determined by the Azure AD settings, which is usually 1 hour. But if you use a PAT, you have control over the lifetime of the token.
