Hotkeys for flicker-free brightness adjustment

[tech-no-sphere]

Hello, Seerge!
I'm new here with my Asus ProArt PX13.
I like G-Helper a lot, but would like to have more customization options (at least through config.json)...
For example, Fn+C and Fn+V hotkeys doesn't work for me, and the single available Fn+F12 is not so convenient shortcut (keys are in opposite corners of the keyboard). Would be great to have possibility to map at least two additional combos instead of Fn+C and Fn+V.
But what I want to ask now is about the flicker-free brightness adjustment. Combos Fn + Ctrl + F7 / F8 / Ctrl + Shift + Alt + F7 / F8 - don't work for me. So can I add other hotkeys for adjusting it just like I do with standard Fn+F5/F6 on my keyboard? This option me and my eyes would appreciate a lot!
Hope to get kind replies to my questions. Thanks!
