Sharing one dashboard by URL (readonly)

When I search for this option, it points me to the topics where people share their dashboard showing how great they are. I love this, but it is not what I am looking for.

I want to share one dashboard by URL to another system (for NarrowCasting purposes). Is there an option to generate a URL with a unique id which shows this Dashboard without having to login?
Almost the same as casting a dashboard, but than in a webbrowser.

Such as: https://my.homeassistant.url.com:8123/<unique_id_trusting_connection_to_dashboard>
