I didn't find any instructions for contributing, so I hope it's fine just to send the PR like this.

I see the complaint about signing off the commit, but I'm assuming an actual project member should sign-off and not me?

Please let me know if I need to do something else.

Thanks for your contribution. About the failing DCO, you may want to checkout the details at https://probot.github.io/apps/dco/ This can be fixed by adding a Signed-off-by messaage to the commit. You can easly amend that to the existing one using git commit --amend --signoff

[juliusknorr]

Btw. the ticket you linked seems to be unrelated, maybe there was a mistake with that?

[lu-fennell]

Oh.. yes the link was totally wrong. It's nextcloud/server#24618 I wanted to link to. I fixed it.

I also signed of the commit, now. Thanks for the explanation
