Getting MQ Exception: MQRC_NOT_AUTHORIZED

I have installed IBM MQ and IBM MQ Explorer by using the below steps mentioned in the PDF file,

After that, I want to access the queues list from a C# console app (.NET Core 8.0) as below,

`using IBM.WMQ;
using IBM.WMQ.PCF;
using System.Collections;

namespace IBM_MQ_Testing
{
public class Program
{
public static void Main(string[] args)
{
string queueManagerName = "QManager01";

 Hashtable connectionProperties = new Hashtable { { MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED }, { MQC.CHANNEL_PROPERTY, "SYSTEM.DEF.SVRCONN" }, { MQC.HOST_NAME_PROPERTY, "YOUR-PC-NAME" }, // Or your machine name or IP { MQC.PORT_PROPERTY, 1414 }, }; try { MQQueueManager queueManager = new MQQueueManager(queueManagerName, connectionProperties); Console.WriteLine($"Connected to Queue Manager: {queueManager.Name}"); // Create PCF message agent IBM.WMQ.PCF.MQCFH header = new IBM.WMQ.PCF.MQCFH(IBM.WMQ.PCF.CMQCFC.MQCFC_LAST, IBM.WMQ.PCF.CMQCFC.MQCMD_INQUIRE_Q_NAMES); IBM.WMQ.PCF.PCFMessageAgent agent = new IBM.WMQ.PCF.PCFMessageAgent(queueManager); // Create PCF request IBM.WMQ.PCF.PCFMessage request = new IBM.WMQ.PCF.PCFMessage(IBM.WMQ.PCF.CMQCFC.MQCMD_INQUIRE_Q_NAMES); request.AddParameter(MQC.MQCA_Q_NAME, "*"); // Wildcard for all queues // Send PCF request IBM.WMQ.PCF.PCFMessage[] responses = agent.Send(request); foreach (IBM.WMQ.PCF.PCFMessage response in responses) { string[] queueNames = (string[])response.GetParameterValue(MQC.MQCACF_Q_NAMES); foreach (var name in queueNames) { Console.WriteLine("Queue: " + name.Trim()); } } queueManager.Disconnect(); } catch (MQException mqe) { Console.WriteLine($"MQ Exception: {mqe.Message}, Reason Code: {mqe.ReasonCode}"); } catch (Exception ex) { Console.WriteLine("Error: " + ex.Message); } Console.ReadLine(); } }

But when I run the above console app from Visual Studio 2022 in ADMINISTRATION mode, it throws the following error,
