I had to add the paths with an leading and ending space and $HOME to work properply.
So kb_hint_confs=" $HOME/.config/hypr/silos.conf $HOME/.config/hypr/scratchpads.conf " works but kb_hint_paths="~/.config/hypr/silos.conf ~/.config/hypr/scratchpads.conf" for it to work properly on my end. I haven't understand at first what was meant with spaces, could be only neccessary for me 'cause my fork is modified a lot.

@dieBakterie thanks. got lazy to treat it as array lol.

now you can just use the bash array conventions

kb_hint_conf=("file1.conf" "file2.conf") ﯦ add a custom keybinds.conf path (add it like an array)
