Disable Face Analyzing Permission

[saltshaker]

Hello, I have allowed Face Analyzing when I wanted to try a bunny filter on my face. It was fun. Now I would like to undo that permission as It's a privacy concern for me. I have put A LOT of time trying to find out how to do that- searching the settings and online. This is unbelievably complicated/ simply impossible. I was not able to find anything related. 

Any help appreciated, Thanks.
