Raw html within description field?


I’m trying to develop a Duo MFA component and am stuck trying to display the iframe which is required on setup and login.

It appears that it’s only possible to display a title and description as seen within the strings.json file here https://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/auth/strings.json

I’m unfamiliar with the markup language used. Is it possible to put raw html within these fields?
