I have a user who wants to add an iframe into a Kibana dashboard to display some data from a dashboard in his application alongside the Kibana dashboard. For various reasons, he can export the specific data in an iframe, but it can't easily be ingested into Elasticsearch.
Inasmuch as there is an official markdown specification, it allows for embedding html tags, so this should be as simple as creating a markdown visualization with the embedded iframe tag, but the markdown visualization simply shows the inserted code as text, like so:
<iframe width="560" height="315" src="https://www.youtube.com/embed/DR-zJXxtefE" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen>YouTube Video</iframe>
