Can I display card Description in a different format

Question

I have just discovered Mermaid for Markdown and so have set about building a Power-Up to render said markdown as an image on a card. My thought was to let the user put the Markdown in the description like this: ```mermaid sequenceDiagram participant Alice participant Bob Alice->>John: Hello John, how are you? loop Healthcheck John->>John: Fight against hypochondria end Note right of John: Rational thoughts
prevail! John-->>Alice: Great! John->>Bob: How about you? Bob-->>John: Jolly good! ``` I've looked at the documentation but I'm not sure which event to hook so I can retrieve the card Description and then render the image in an iFrame. I was thinking card-detail-badges or maybe format-url... Does anyone have an recommendations? TIA Paul

I will try hooking the card-back-section as you have suggested though... :D

Thanks @Michael Pryor , sounds like I don't really understand the anatomy of a card from a developer perspective.

Does such a thing exist in the documentation anywhere?

Power-Ups get a section on the card back that you could control. It wouldn’t change how the description was rendered but below it on the card back you could draw whatever you wanted in that section.
