molecular orbital diagrams with latex: In the images you can see the latex code and the image it produces. I do not know how to change the labels of the molecular orbitals. I want to label the $2$p pi molecular orbitals from $2$pi$\_$y$,2$pi$\_$z to pi$\_\{2$p$\_$x$\},$ pi$\_\{2$p$\_$y$\}$ and also change the label of the sigma molecular orbital from $2$ sigma$\_$x to sigma$\_\{2$p$\_$z$\}.$ How do I do that?

here the code I've used:

$\backslash$documentclass$\{$standalone$\}$

$\backslash$usepackage$\{$modiagram$,$chemfig$\}$

$\backslash$usepackage$[$version$=3]\{$mhchem$\}$

$\backslash$begin$\{$document$\}$

$\backslash$MOsetup$\{$
