How to get rid of floating bubble on a Pixel 6?

I am using Prey on my Pixel 6, and this little bubble is getting really annoying. It’s always in my way somehow. I move it, and later on it’s in my way for something else. I didn’t have this on either of my 2 previous phones (this is my first Google-branded device).

How the heck do I get rid of it? I can tolerate the notification area bit, but this bubble is driving me up the wall.

Hello. Same problem with me. Floating button in LineageOS 19, don’t need it, don’t want it.
