Hello, I need some help with my new android TV. I got two remotes with it: a normal one and one with voice control than I can't seem to figure out how to use.

I go to press the microphone on the remote but nothing happens, it just doesn't do anything. It's like it doesn't hear my voice at all. Now, I don't know what I'm doing wrong, tbh. Maybe some of them experienced the same and can help me?
