Tico the Agorist

I received my remote today, I’m so excited to finally replace my dead Harmony remote. One thing I need help tho is trying to make it work with a Xiaomi TV, I’ve tried a couple other Android TV brands but doesn’t seem to work, I got the rest of my equipment working. Is there another brand I should tried (already tried with TCL and Samsung)? Will there ever be support for Xiaomi?
