Disable AI companion permantly

[april26]

I don't want the AI companion attending my meetings. I've switched it off in multiple places all over my account, and yet it pops up as a participant every single time. My meetings are private, I don't want any other parties listening in. It's a massive security black hole. It's so annoying to block it manually for every single meeting. 

How do I uninstall it, when it was never installed in the beginning. I went through the AI support, and everything it suggested is already off.
