Description

I have been running into System.InvalidCastException when trying to set up a GraphQL subscription. I have tracked the error occuring to line 318 of GraphQLHttpWebSocket in the repo:

`var certs = ((HttpClientHandler)Options.HttpMessageHandler).ClientCertificates;`

I am using .NET Maui and am not entirely sure if I am doing something wrong or if it is a MAUI or repo issue.
