How do you edit a card?

When you are using the editor, if you at the very beginning of a section and paste a link, it will attempt to create a “card” for that URL with a picture and description instead of showing just the URL there (see picture above). How do you edit that card? I want to modify the URL used, but it seems I can only delete the whole thing. This is an issue when editing older posts as I don’t know the exact URL used, so my only solution now is to preview the page, copy the link from the card on the preview page, go back and delete the card and add the updated one. That seems a bit of a hassle when you probably should just be able to edit the url in the editor. Am I missing some special key command or something?
