Use gnome shell gtk theme for title bar

Is your feature request related to a problem? Please describe.

This feature request is not a problem.

Nautilus/file manager uses the WhiteSur gtk theme (mainly the 3 title bar buttons, aligned to left) while in the hyper window it uses its own custom title bar, title bar buttons aligned to right (which is not what I want, see below).
Describe the solution you'd like
A clear and concise description of what you want to happen.
An option to use the gnome shell theme for consistency across applications, which then my current hyper term window would resemble this:

It would use the applied gnome shell application theme.
Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
Do not know of any alternative solutions, but this seems possible considering it's been done in macos

I am trying out a mac os theme for Ubuntu, a gtk called WhiteSur @ https://www.pling.com/p/1403328/

No source files or tests are named. Start by locating Hyper's title-bar implementation and Linux desktop-window integration, then determine how an option could use the applied GNOME/GTK theme; done means the option produces GTK-consistent title-bar buttons and placement on Linux without changing other platforms.
