How to set single key for customization keyboard shortcuts in gnome

I'm trying to set single key to operate anything i want in gnome settings. I'm using Debian-12 and Gnome 43. Settings->Keyboard>View and Customize Shortcuts(Keyboard Shortcuts)->Custom Shortcuts->Add Shortcut->Set Shortcut In Set Shortcut panel, single keys is not detected(neither model nor standard keys, i.e Super, Alt, CTRL, Shift etc. But Function keys could be detected i.e F1,F5...) The thing I'm trying to do is to add single key and run any command by the shortcut or be able to change already available shortcuts by a single key i.e. pressing only super key should open application menu like in pressing in Windows key to open start menu. So far, I've tried to change it by dconf editor and played around with settings; > org > gnome > desktop > input-sources > sources > org > gnome > desktop > input-sources > xkb-options as in this link described but it didn't work. Can you help. Thanks.
