How to add a website link to Trello?

Question

JavaScript

I need to bookmark the site I'm currently on in Trello.
There is an official tool for this https://trello.com/add-card , which, using a bookmark, adds a card with the title of the current page, a link and an image to the yap.
Not satisfied, because the link is added to the attached files, but it is needed in the description of the card. It also annoys that in Safari, when you close the window, it asks for confirmation.
How to create a bookmark that adds the site to the description of the card, the title to the title, the picture to the attached files and the selected text on the page to the description?
Or - how to change the official code so that a link is added to the description?

javascript:(function(win%2Cname%2Cdesc)%7Bwin.open('https%3A%2F%2Ftrello.com%2Fadd-card'%2B'%3Fsource%3D'%2Bwin.location.host%2B'%26mode%3Dpopup'%2B'%26url%3D'%2BencodeURIComponent(win.location.href)%2B(name%3F'%26name%3D'%2BencodeURIComponent(name)%3A'')%2B(desc%3F'%26desc%3D'%2BencodeURIComponent(desc)%3A'')%2C'add-trello-card'%2C'width%3D500%2Cheight%3D600%2Cleft%3D'%2B(win.screenX%2B(win.outerWidth-500)%2F2)%2B'%2Ctop%3D'%2B(win.screenY%2B(win.outerHeight-740)%2F2))%7D)(window%2Cdocument.title%2CgetSelection%3FgetSelection().toString()%3A'')

Thanks in advance!
