HTTPS Client Certs for Samsung Smart TV Web App

I am trying to develop a Samsung Smart TV application as a web app. As part of the requirements, I need to send HTTPS requests. I am doing that using Axios (which it can also be done through the Fetch API). When making the request, I am trying to attach a client cert. The JavaScript sandbox does not allow for this. According to what I have found, it is a function of the browser to perform this task.

I am working with web assembly now and trying to integrate it with a background web worker to intercept all HTTPS calls and send them through web assembly. This seems like a convoluted process. Is there a simpler way to perform this task with Tizen APIs to simply set the client and server certs. It seems like there is something that I am missing.
