How Can I Get The Message Id When Receive Message？

[Cryking]

My Receive Event Code is This, who can tell me how to get the MsgId, I need this to troubleshoot issues.
i'm try to console e.PacketIdentifier for id, but i found it's not. (the output is 1930, but the actual ID is D211978BB4F04EB69FF74575A80ECA4F )
`private async Task Client_ApplicationMessageReceivedAsync(MqttApplicationMessageReceivedEventArgs e)
{
var msg = e.ApplicationMessage.ConvertPayloadToString();

try
{
    var topic = e.ApplicationMessage.Topic;
     ...
}
catch (Exception ex)
{
    _logger.LogError(ex);
}

}`
