Embed home assistant into webpage

So, is there some way how to do this? Meny questions without answer. Seems like it is impossible to show hass in other webpage, right?
I mean no menu, just clean specified dashboard.

I tried cast, tried iframe, tried webpage card (dead project)… any idea?

Did you already try the Kiosk mode?

Still you know you are in HASS, stil you can remove fullscreen. Not fully working. My goal is to embed HASS dashboard into other web or shows only parts of hass dashboard as widgets somewhere else…

Nobody any idea?
