Sidebar webpage tunneled/proxied trhough HomeAssistant

Hi Team,

I’m not sure how to describe it. Is is possible to display any web page on sidebar but proxyforwarded(?) trough HomeAssistant? Like I would like to access router home page http://192.168.0.1/ from any location using HomeAssistant sidebar? It could work with iframe but as long as I’m within local network.

(Im using Docker solution of HA)
