Is it possible to access Dataverse and Microsoft Graph api by single token using AAD auth?

Hi micheleariis 

When I am trying to make an API call to generate a token then getting CORS issue. Here is the code Future<String?> getAccessToken() async {
final String tenantId =
''; // Your Azure tenant ID
final String clientId =
''; // Your Azure application client ID
final String clientSecret =
''; // Your Azure application client secret
final String scope =
'https://graph.microsoft.com/.default'; // Use .default to request all permissions granted
final String tokenEndpoint =
'https://login.microsoftonline.com/$tenantId/oauth2/v2.0/token';

final response = await http.post(
Uri.parse(tokenEndpoint),
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Access-Control-Allow-Origin': "https://abc.in/",
'Access-Control-Allow-Credentials': "true",
'Access-Control-Allow-Methods': 'POST,OPTIONS',
'Access-Control-Allow-Headers': 'X-PINGOTHER, Content-Type',
'Access-Control-Max-Age': '86400'
},
body: {
'client_id': clientId,
'client_secret': clientSecret,
'grant_type': 'client_credentials', // Use client credentials flow
'scope': scope,
},
);

if (response.statusCode == 200) {
final Map<String, dynamic> tokenResponse = jsonDecode(response.body);
print('tokenResponse==$tokenResponse');
return tokenResponse['access_token'];
} else {
print('Failed to generate token: ${response.body}');
return null;
}
}
