Access CRM Online V9.1 Reporting Services from plugin code

Hello Experts,

I'm currently trying to access with ADAL authentication Token, but this error is happening

Request for the permission of type 'System.Security.Permissions.EnvironmentPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

string resource = "https://ServerURL.crm.dynamics.com/";

HttpResponseMessage response;
string clientId = "XXXXXXXXXXXXXX";
string clientSecret = "XXXXXXXXXXXXXX";
string authorityUri = "https://login.microsoftonline.com/"Domain"/oauth2/authorize"; // i tried this "login.microsoftonline.com/Tenantid" as guide, and I got same issue

AuthenticationContext authenticationContext = new AuthenticationContext(authorityUri, true);

var credential = new ClientCredential(clientId, clientSecret);
var result = await authenticationContext.AcquireTokenAsync(resource, credential);

var token = result.AccessToken;

HttpClient request = new HttpClient();
request.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
HttpRequestMessage req = new HttpRequestMessage(HttpMethod.Post, completeUrl);
req.Method = HttpMethod.Post;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

response = await request.SendAsync(req);
var responseText = await response.Content.ReadAsStringAsync();

var x = responseText.LastIndexOf("ReportSession=");
var y = responseText.LastIndexOf("ControlID=");

string[] ret = new string[2];
ret[0] = responseText.Substring(x + 14, 24);
ret[1] = responseText.Substring(y + 10, 32);

I followed this link to create the Authentication token: https://www.c-sharpcorner.com/article/generate-access-token-for-dynamics-365-single-tenant-server-to-server-authentica/

i hope some help, Kind Regards
