Hi!
I don't have the "video" icon at my Trello Premium cards. I am using Trello by Chrome.
If you go to Loom.com they have both a desktop and a browser extension (so you don't really need a button on the card).
You can just click that Loom button in the browser and it will record and give you a link to add to the card. The video will still embed if you make it the title of the card for example.
