Based on the information from the Widget Connector Macro's documentation, we are supporting YouTube.

The YouTube Short videos (do not confuse it with the short URLs like https://youtu.be/..) are not rendered as it should.

Suggested Solution

Provide support for YouTube short videos.

Workaround

Instead of using the regular YouTube Shorts link: https://www.youtube.com/shorts/<video_id>
The following URL format can be used: https://www.youtube.com/watch?v=<video_id>
