Request for the "show more" feature in embed messages.

Would be nice if we could implement the YouTube's "show more" feature inside the embed messages. So once the user clicks on "expand" or "show more", it'll extend the embed and show the whole text (or an image), that couldn't fit before. As of now, putting plenty of text inside the embed doesn't make it look user friendly, but sometimes it's necessary, because it's still better to have one embed that can contain everything, rather than 2 smaller ones in a row.
