I recommend reading up and learning more about flatpaks and their sandboxing. Flatseal is just a GUI implementation of the flatpak CLI.

You can also very quickly download Flatseal for yourself to put your own eyes on it. Everything is labeled and has tooltips.
Rename all the coreutils. Confuse yourself and the hackers!
