iOS Notes: Where is function „Duplicate“?

I wanted to use the notes app to create many other notes based on a template. The template is a normal note where I use predefined headings that I don’t want to type in again whenever I create a new note for my purpose.

Now here is the funny thing: When I use the share function on my template note, I can only see „Copy“, but no „Duplicate“. On my iPad and on my Mac I can see it. I have an iPhone 15 and I am on the lastest iOS version. To see if I just missed something, I googled, but I only found these instructions that only confirm that the „Duplicate“ function should be where I expected it:

Does anybody else have this problem?

Please don’t send me replies like „Have you updated your iPhone? Restart your iPhone 100 times, then it works.“ Thanks!
