Hello Quang Minh,

You need to provide the video url in the Link attribute, and iframe as the Link anchor.

What's the url you need to put on the Link attribute? In our examples you can see this url:

https://player.vimeo.com/video/157168801?autoplay=1&title=0&byline=0&portrait=0

This is the src attribute of the code you get when you want to embed a video. You can use Vimeo, Youtube or whatever you need, you only need to get the src attribute.

Kind Regards
