🐛 error: unexpected argument '--generate-completion' found

[freeformz]

I tried out what I found here: https://dandavison.github.io/delta/tips-and-tricks/shell-completion.html

And got the error you see below. I tried it first with the homebrew install, then the downloaded version directly from github. Same issue with either version.

$ ./delta-0.16.5-aarch64-apple-darwin/delta --generate-completion fish
error: unexpected argument '--generate-completion' found

  note: argument '--grep-context-line-style' exists
