How to send a message with a link to YouTube video, in a way that the video can be played within WhatsApp?

[AmitRaphael]

When I manually type a link to YouTube video into a WhatsApp message, after waiting a few seconds, the message will have on top of it, a playable image of the video that will allow playing the video within WhatsApp chat.
Is there a way to send the message that way?
Thanks!

This is just an ExtendedTextMessage with several properties.
Currently, I'm using github.com/Junzki/link-preview to get the meta info.

Important: the URL should be on the text to make it work

The previewType will be sets of these :

const (
	ExtendedTextMessage_NONE        ExtendedTextMessage_PreviewType = 0
	ExtendedTextMessage_VIDEO       ExtendedTextMessage_PreviewType = 1
	ExtendedTextMessage_PLACEHOLDER ExtendedTextMessage_PreviewType = 4
	ExtendedTextMessage_IMAGE       ExtendedTextMessage_PreviewType = 5
)
