How to find the part of cspell.json ?

[collegeimprovements]

I'm using neovim and when i add word to user dictionary the error disappears from diagnostic.
However I'm not able to find cspell.json file anywhere.

Is there a command like CocConfig or something to open cspell.json file ?

I've configured a path in coc-config.json ("cSpell.import": ["~/.config/nvim/general"]) as well, but when i add word in dictionary it doesn't appear there.
Is there a way to configure the default path for coc-add-word-to-user-dictionary ?
