Gdbus wayland: get size and position of a window

Question

I cannot find any examples on how to use gdbus to get the position and rect size of a window.

I am able to get the window's pid using code from other stackoverflow questions, but there is no way to get that window's current position relative to the screen.

This is bash code I found that can let me get the active window's pid, but I also need its rect
