RabbitMQ Producer over SSL in C#

Question

I'm trying to convert the following RabbitMQ Producer over SSL code from Python to C#. I'm not sure how I can specify all these configurations for the certificates. How do I do that?

I read this StackOverflow question, but this python code uses chain of certs.

Python

context = ssl.create_default_context(cafile="./ca.pem")
context.load_cert_chain("./cp_certificate.pem", "./cp_key.pem")
ssl_options = pika.SSLOptions(context, "localhost")
credential = pika.PlainCredentials('rabbitmq', 'rabbitmq!QAZ')

conn_params = pika.ConnectionParameters(host="90.44.213.24", port=5671, ssl_options=ssl_options, credentials=credential, virtual_host='op_vhost')
connection = pika.BlockingConnection(conn_params)
channel = connection.channel()
channel.basic_publish(exchange='custom_flow', routing_key='custom_routing', body='body', mandatory=True)

Current C# code

using System.Text;
using System.Text.Json;
using RabbitMQ.Client;

var factory = new ConnectionFactory
{
    HostName = "localhost",
    Port = 5671,
    Ssl = new SslOption
    {
        Enabled = true,
        ServerName = "localhost"
    }
};

using var connection = factory.CreateConnection();
using var channel = connection.CreateModel();

channel.ExchangeDeclare("custom_flow", ExchangeType.Direct, arguments: null);

var count = 0;
while (true)
{
    var message = new
    {
        Name = "Producer",
        Message = $"Hello! Count: {count}"
    };
    var body = Encoding.UTF8.GetBytes(JsonSerializer.Serialize(message));

    channel.BasicPublish("custom_flow", "custom_routing", null, body);

    count++;
    Console.WriteLine($"Sent message: {message}");

    Thread.Sleep(1000);
}
