Description of issue

I am new to homebrew and not great with the Terminal on macOS.
I installed homebrerw from the macOS .pkg at github.com/Homebrew/brew/releases/download/4.3.10/Homebrew-4.3.10.pkg onto a non-admin account on macOS 14.5 on Apple Silicon.
Now, when I run the uninstall command referenced at https://github.com/homebrew/install#uninstall-homebrew I am told that I need sudo permissions.

I have a what seems to be a fully populated folder at /opt/homebrew.

How do I completely uninstall homebrew?
