I installed a capture card recently that needed a kernel extension and after agreeing a confirmation box to install the extension I couldn’t find anywhere in the settings to remove it. In the end I just deleted the file and rebooted.
I had Teams in the browser ask if it could access files in my Downloads directory which I mistakenly agreed to, this took a good ten minutes to find and revoke and I can’t remember off the top of my head where the setting even was.
A lot of this is down to more granular privacy and security settings but it’s difficult to find the settings you are looking for.
