@Gitesh-Yeole
Did you check the Note part in document ?

Note : On X11 you need to have a composite manager running, 
and the X11 specific _NET_WM_WINDOW_OPACITY atom needs to be supported by the window manager 
you are using.

Is this the issue in your case. ?

[Gitesh Yeole]

Yes exactly this is the issue but I am not sure which composite manager I should use and how to set atom

I don't know at what level this one works so I can't comment on what you need to modify there.
