Access energy distribution card from internet

I would like to have kiosk-like access to a single certain HA webpage (card). More specifically, I would like to show the energy distribution card (the shiny graph with moving dots) on my Dakboard.

How do I do this ? I can create a user for dakboard, and give this user a new dashboard with the energy distribution card as “home page”; but how can I access this page without logging in from the internet ?

Are there any other ways to open a specific HA webpage without logging in (make them “public” so to speak)? I understood API keys are no longer maintained.
