Unable to install shell completions in ZSH

[Wulfheart]

Hello,

I tried several options and I think that this is a skill issue but I would greatly appreciate any assistance you can offer. I added it (analogue to my eval "$(atuin init zsh)") with eval "$(just --completions zsh)" to my ~/.zshrc and I get the error message "_arguments:comparguments:325: can only be called from completion function". How can I install the autocompletions?

just --completions zsh is used for generateing a completion script. I used just --completions zsh > ~/.oh-my-zsh/completions/_just.zsh.
I am a oh-my-zsh user. oh-my-zsh had added this path to $fpath and loaded it.

I guess autoload -U compaudit compinit will also work if you don't use oh-my-zsh but I never try.
