Orlando Moreno (ID: 00000043967a8398) Voted 1 ★ - Updated 02/21/2023 It doesn't work. Not on custom-added channels, but not even those in the built-in list.

Edsknife (ID: 0000005f7106ddf5) Voted 4 ★ - Updated 05/23/2022 I remember it working before, but it wasn't working today; searched "Ukraine" and all the results were mainstream. I've always slowly lost functions of the extensions I use; there has to be a better way. Could probably do it better without the Chrome Web Store. Might have better luck on Itch.
