A few months ago I was able to see and use Loom within Trello boards.
To date, however, I can no longer see the icon at the bottom of the various lists.
Hi @Pietro Marino 👋
Welcome to the Community! Unfortunately, the Loom integration was a beta release and they've decided to currently remove it, although they hope to offer a Loom Power-up for Trello in the future.
If it's useful there is a Loom Chrome extension available that functions quite similarly as the integration.
I hope this helps but if you have any other questions just ask away 😃
All the best,
