Most CMS don't allow IFRAME integration due to security concerns. But they do support showing an external image.
At my company we have a couple of systems to track projects, and they support Markdown, which allows to insert inline images.
I would like to insert parts (frames maybe?) of a Board, for example a Milestone chart. Preferrable, I would like to have a public URL link (with an obscure url), because Miro rarely stays logged in (some users may not even use it so much).

Thanks!!!
