Logitech G hub LUA Script

Hello, I have a small problem. My friend and I have been trying to create a script for a game together. Could someone help us? We're stuck on how to set hotkeys in this script. We've been trying for weeks but haven't made progress. For example, when pressing the key 9, we want the script to switch to a different action, like changing from Operator X to Operator Y. Thank you in advance!
