install Downloader by AFTVnews on your Android TV, open it and enter kutt.it/stn_beta or kutt.it/stn_stable, then read, understand and confirm the security prompts. (You can also enter 79015 (for beta) or 28544 (for stable), but this requires an extra step to install the AFTVnews Downloader browser addon if you haven’t already.)
The AFTVnews Downloader is available on both Google Play and Amazon Fire TVs. After installing SmartTube, it can self-update on its own without needing another app.
It supports casting via the YouTube phone app (or YouTube ReVanced app).
It isn’t available on my TV apparently. I guess I need to learn how to side load on the TV now

Wow, thanks! I had actually figured that out myself, maybe should have mentioned it. First video went really well
