How to use semi automatic missile (SACLOS) on a heli with HOTAS?

I am having issues keybinding semi automatic missiles on X52. Theres keybind for missile control y axis and x axis but this doesnt seem to control them ? what do they control if not the semi automatic missiles ? can i actually key bind missile control separately ? or is it same as on ground vehicle where you need to use WASD ?

All missiles on helis are mouse aimed. Whatever you have set to move the mouse, is what you will use for the atgms.

The wasd missile keybind is for a couple ground atgms that are manual.
