@tooomm, can you double-check? I think this should work for your use-case.
Perhaps you can even test it on your repo.

I hope this works:

  uses: lycheeverse/lychee-action@use-temp-path

@MrG9090, FYI, please don't approve PRs, especially not if they got merged. That's bad form and looks like spam. I expect you mean well, though. 😉

Okei, in sorry :)
