My large fingers are always bumping the microphone button accidentally. I never use the speech to text feature, so is there any way to disable this icon altogether?

I've tried revoking microphone permissions, but the icon still appears. In fact, when I click it, it says "Google" and "speak now," so I'm not even sure what Google is doing in Fennec since I use a SearXNG instance as my default search engine.

This leads me to believe it might be some intrusive Android "feature," but I'd still like it gone, one way or another.

Anyone know how to remove this? Please and thank you!
