Self Hosted Tensorboard support with user auth

Hello,

I want to be able to securely share Tensorboard sessions with other people. I know I can simply expose the remote host publicly, but this method is not secure, so are there any resources/documentation to do this with proper user authentication so that anyone that has my remote host IP/port cannot see my training logs? I would use tensorboard.dev, but since that's been shut down it's no longer a viable option. I would also be interested if there's any way to fetch the static HTML from the remote host running the Tensorboard service, and inject it into an iFrame in my own web app.

No file, test, or entry point is identified; start by reviewing TensorBoard's current self-hosting and authentication documentation and the existing issue discussion. Establish whether authenticated sharing or fetching content for an iframe is supported or needs a new design, then define the documentation or implementation scope before work begins.
