From the debugger, I could gather these screenshots for 2 different workflows — one called Fixum and another one to switch Audio Output.
The steps I had followed were:
1. Open a terminal and run xcode-select --install
2. Wait for the installation to complete
3. Verify installation by trying to reinstall
4. Terminal returned "xcode-select: error: command line tools are already installed, use "Software Update" in System Settings to install updates"
