I tried ReVanced YouTube on a Xiaomi TV. It worked well, settings and all, except for navigation in YouTube. I used the Bluetooth Remote smartphone app for navigating YouTube.
The Bluetooth Remote is an excellent open-source app; it is free, contains no ads, features a Material You design, includes a D-pad and touchpad, supports mouse and keyboard functionality, and has a "Gyroscope" setting that allows you to wave/tilt your phone to move the mouse cursor across your Android TV screen.
