Howw to configure IssuedSecurityTokenParameters in .NET 6

Question

We have our WCF services which requires custom binding and additional parameters. We have created its custom bindings and passed additional parameters in .NET 4.8 framework. Now we are migrating it to .NET 6. After upgrading the project getting two errors as "IssuedSecurityTokenParameters does not contains a definition AdditionalRequestParameters and IssuerMetadataAddress. We have added System.ServiceModel reference in our .NET 6 project. Code is as below

 public Binding CreateBinding(string customCode, string serverName, string msLogon)
    {
        var issuedSecurityTokenParameters = CreateIssuedSecurityTokenParameters(customCode, serverName, msLogon);

        var issuedTokenOverTransport = SecurityBindingElement.CreateIssuedTokenOverTransportBindingElement(issuedSecurityTokenParameters);
        issuedTokenOverTransport.MessageSecurityVersion = MessageSecurityVersion;
        issuedTokenOverTransport.LocalClientSettings.MaxClockSkew = TimeSpan.FromMinutes(5);

        SecurityBindingElement secureConversationBindingElement = SecurityBindingElement.CreateSecureConversationBindingElement(issuedTokenOverTransport);
        secureConversationBindingElement.MessageSecurityVersion = MessageSecurityVersion;

        BinaryMessageEncodingBindingElement binaryMessageEncodingBindingElement = new BinaryMessageEncodingBindingElement
        {
            MaxReadPoolSize = config.MaxReadPoolSize,
            MaxSessionSize = config.MaxSessionSize,
            MaxWritePoolSize = config.MaxWritePoolSize,
            ReaderQuotas =
            {
                MaxArrayLength = config.MaxArrayLength,
                MaxStringContentLength = config.MaxStringContentLength,
                MaxBytesPerRead = config.MaxBytesPerRead
            },
            CompressionFormat = config.CompressionFormat
        };

        TcpTransportBindingElement tcpTransportBindingElement = new TcpTransportBindingElement
        {
            MaxBufferPoolSize = config.MaxBufferPoolSize,
            MaxBufferSize = config.MaxBufferSize,
            ConnectionBufferSize = config.ConnectionBufferSize,
            MaxReceivedMessageSize = config.MaxReceivedMessageSize,
            TransferMode = TransferMode.Streamed

        };

        var streamSecurity = new SslStreamSecurityBindingElement { RequireClientCertificate = false };

        CustomBinding binding = new CustomBinding()

Can you please give any reference, how can we migrate this to .net 6?
