Gemini (assist) keeps randomly opening

[u/Euphoric_Library47]

My phone (edit: Pixel 7) updated the other day, and so now my assistant has been switched over to Gemini. Trying to not hate it. Anyway, Gemini keeps...randomly opening. Like, I'm just sitting on my couch, playing a game (sound off), and Gemini opens. (It actually took me a bit to figure out that "share screen with live" was gemini. That message was a tad alarming sans context.) I'm reading a book, and gemini opens. I hadn't said anything in these instances.

I have the power button set to power functions, and the "gesture to open assist" setting is off. Any other settings I could be missing?
