Cannot make issue unconfidential

I accidentally created a confidential issue in some gnome repository, I want to change the issue confidentiality back to un-confidential, but I can’t see the “Edit” button in the “Confidentiality” section in the sidebar of the issue?

Do you have some sort of adblocking software or something that might cause this not to popup? According to the docs, there are two ways to do it: Confidential issues | GitLab

I have request the repository maintainer to make the issue public in the earlier, now, this issue is become visible to everyone, it seems the maintainer has the permission to do that instead of the issue creator.
