there's an opt-in File Explorer context-menu integration in the installer (wizard) GUI.
I have ticked this option.

The problem is when I try to pop up the powershell in empty space of a folder, you provide submenus.

It's boring for me to choose open here and open as Administrator.
I already set it open as Administrator by default, so I hope you can make it as "git bash here" directly without submenus.
