If you tinker with programming , you can look into ags - aylurs gnome shell. His dotfiles include an app launcher in it, adding this functionality should not be too hard.

Do you need Krunner as a generic applauncher or do you use other features too?

I had problems with 535-104, couldn’t launch into Hyprland, tried a quick install of Plasma (though with hypr XDG) and that was laggy as all hell. Dropped back to 535-98 and it runs smooth again.
