Ad-free Twitch app for Fire TV? (SmartTube equivalent)

Hey everyone,
I'm currently looking for a decent app for the Fire TV Stick to stream Twitch completely ad-free.
Is there currently a stable alternative with a built-in adblocker that can be sideloaded (e.g., via Downloader)?
SmartTube works great for YouTube is there something similar out there for Twitch?
Thanks in advance for your tips!
