How to troubleshoot messages sent from local compter to Azure IOT Hub using WireShark?

Question

I am sending messages from my C# application to IOT Hub using below code snippet.

 public async Task<MessageToTargetStatus> ForwardMessage(byte[] message)
    {
        var messageToSend = new Microsoft.Azure.Devices.Client.Message(message);            
        await iotHubClient.GetDeviceClient().SendEventAsync(messageToSend).ConfigureAwait(false);
        return MessageToTargetStatus.Success;
    }

Messages are successfully received at the Azure IOT Hub

Now I want to test my security of these messages and trying to verify these messages in WireShark.

I see many records in WireShark, but I am not able to figure out which is my messages sent to IOT Hub.

When I send single message from Device Explorer, I see many communication records in WireShark. Which protocol I should be filtering?
