I use my Finder replacement to access so many places on my computer. I consider it a substantial risk, but I do it anyway.
I don't.Do you, or does anyone else, know how to get a full list of all permissions I've granted or denied to QSpace?
But are you mad? You are running a bit of software that you don't trust - remove it thoroughly.
macOS permissions are about letting you know what access an application requires ** - giving you a chance to say that as a consequence you don't want to run the app.
macOS permissions are NOT about allowing you to safely run untrusted applications.
**Alternatively you might say that app permissions are Apple trying to scare you from running apps not from the Apple App Store. In which case just allow them.
