How to get file from Azure services(Azure blob storage) using Azure Service Principal Name(SPN) using C#.net?

Question

In General, I want to get files from the Azure blob storage account using C#.net, and I have an SPN name. I have tried the following ways to do it.

Note: Here Authentication key stored in KEY Vault and Azure admin provide us only SPN Name

Way 1:

private static async Task<string> GetAccessToken()
string accessToken = "";
            try
            {
                var authContext = new AuthenticationContext($"https://login.windows.net/{TenantID}");
                var credential = new ClientCredential("{ClientID}", "{SPN Name}");
                var result = await authContext.AcquireTokenAsync("https://storage.azure.com", credential);

                if (result == null)
                {
                    throw new Exception("Failed to authenticate via ADAL");
                }
                accessToken = result.AccessToken;
            }
            catch (Exception ex)
            {
                System.Diagnostics.Trace.WriteLine("Exception for get Blob container" + ex.Message.ToString());
            }

Way 2:

private static async Task<string> GetAccessToken()
 var serviceTokenProvider = new AzureServiceTokenProvider();

            var keyVaultClient = new KeyVaultClient(new KeyVaultClient.AuthenticationCallback(serviceTokenProvider.KeyVaultTokenCallback));
          
            SecretBundle secretValue = null;
            try
            {
                secretValue = await keyVaultClient.GetSecretAsync("{KeyVault URI}", {SPN_Name});
            }
            catch (Exception kex)
            {
                System.Diagnostics.Trace.WriteLine("Exception for get Blob container" + kex.Message.ToString());
            }
           return secretValue.Value;

Following code to Access File from Azure Storage

public static async Task<List<IListBlobItem>> GetBlobContainer( string containerName)
        var token = await GetAccessToken();
                TokenCredential tokenCredential = new TokenCredential(token);
        //here i am getting all one day file
                DateTime date = DateTime.Now;
                date = date.AddDays(-1);
               
                StorageCredentials _objectCrentials = new StorageCredentials(tokenCredential);

                CloudBlobClient blobClient = new CloudBlobClient(new Uri($"{Storage Account URI}"), _objectCrentials);
                // container
                CloudBlobContainer blobContainer = blobClient.GetContainerReference(containerName);
                IEnumerable<IListBlobItem> listOfBlob = blobContainer.ListBlobs().OfType<CloudBlob>()
                   .OrderByDescending(b => b.Properties.LastModified > date);
                //check her do you get any list
                _list = listOfBlob.ToList();

Way 2 have gives this error.
