I want to trigger a key combo on Presses, not after Presses+Release

[jackthenewbie]

I'm currently has this setup. Ctrl+space only trigger after I release BTN_EXTRA. At first I thought it just I set this up wrong, but after doing similar setup with SIDE_BUTTON trigger letter "e". Letter e only appear after I release the side button.

My question is: is it possible to trigger output immediately when I presses, not press+release? I appologize as the docs is too long, so I dont know where to look.

Edit:
My specs
OS: Linux lite 7.0 (base ubuntu 24 lts)
Gnome 46 Wayland
I installed input-remapper through apt install input-remapper
