Jellyfin on Roku TV?

I'm interested in using Jellyfin. I learned that you can install the Jellyfin "channel" on any Roku device to stream to it. I have a TCL Roku TV and when I search for Jellyfin nothing appears. Also when I follow the link from Jellyfin's website to Roku's website it redirects to the main channel page and when I search for it there it doesn't appear.

Is Jellyfin still available on Roku? I can't find anything online indicating that it shouldn't be.
