Anyway to show dakboard in iframe card through HA

I like Dakboard interface for the free version and cant find anything with HA that is even close. Dakboard lets you connect displays by inputting code from link. I used the link that it generates and put inside webpage card in HA but it just goes to the main website. It doesn’t let me enter the device ID. The website within card also does not let me interact with it like trying to login there. Anything else I can do?

Where you able to find a solution? I am trying to do the same.
