GLFW blocks manually configured native window properties?

support
1

I want to alter the native properties of a glfw window
It is possible, but the specific property im after (rendering the window behind all other windows) isnt working
I know for a fact this property works as i made an xlib window from scratch to test. Is GLFW blocking me from assigning this property? Is there an easy solution to this?

Code is below.

FYI Cross compatibility is not a concern rn

/*
If you would like to try it out heres the build command
`gcc -o main -Iinclude main.c -L./ -l:libglfw3.a -lm -lX11`
 
include contains the default glfw include folder
libglfw3.a is in the root of the project
