Show Cerbo's Remote Console on NodeRED dashboard

As displaying node-RED dashboard on Cerbo is almost
impossible,
I tried to show Cerbo’s Remote Console on the dashboard using ui-template or ui-iframe nodes,
with iframe width=“840” height=“360” src=“http://venus.local

While the code works nicely as separate HTML, on dashboard it shows empty frame.
I know, that Remote Console needs Canvas capability of the browser, but ui-template should be able to handle this. I tested everything, still got empty frame.

Any ideas? Thanks.

Well, needs to be https and exact IP, not venus.local. Then iframe node with 16x7 size works perfectly including Cerbo remote.
