Looking to make push to talk macro.

I recently switched from the logitech g600 to the corsair m65 pro. I have been looking to make my foward button push to talk in game which is the k button for me normally. I also am looking to make the back button * which is my teamspeak/discord push to talk button. If anyone could tell me what i need to record and how to set it up so the macro runs until i let go of the button that would be great! Oh and by the way i know i suck at making macros)

 

EDIT: I am using CUE 2.4.66

Make a new action -> remap key -> select key you want other key to imitate -> DO NOT enable imitate holding. -> Now you have a working push to talk key.
