Embedding external content and videos via IFrame

[TCK]

Hello there,

I'm currently creating a notebook which contains a training course for data engineering.

For certain topics it would be nice to embed external resources like Youtube videos so participants do not have to leave the notebook to watch the video and then come back. 

Including an IFrame via displayHTML -> IFrame works but participants need to be actively connected to a cluster in order to run this step first before they can see the video.

I would rather want to include a video via markdown just like this:
```

%md

<iframe src="xxx" ...></iframe>
```

In most IDEs this just works but in Databricks the resulting IFrame seems to get its src property stripped away.

Is there any way to achieve this easy mode of embedding external content in my notebook?

Thanks in advance!

Did you try using displayHTML() ?

Yes, like I said in the original post, displayHTML works but needs to executed as a step first which requires a running cluster in order to display the video.
