We want to connect our .NET application to elasticsearch 8.5.2 single node cluster.  
We want to use https and ssl communication.

We have 3 certificates from our CA.  
root , intermediate and main along with private key.

The certificates have been imported to the browser to disable security warning.

We want our .NET code to use SSL communication with the ES server .

Please share the steps we need to do on client machine and sample code if possible.
