I was searching the web for how to add volume control to my HA dashboard for Sonos. I found this post which had a dashboard control that looks awesome:

My dashboard uses a Media Control Card but it doesn't have volume. I can't figure out how to have that Sonos card shown in the above link (and attached to this post). I have the Sonos Integration in HA but can't find any Cards that look like the one in the screenshot.
Anyone familiar with this and can clue me in?
