First of all: I'm not a technic, but I asked the AI to build me a Sigil plugin in order to automatically search and replace old german orthography to the new one. The AI helped me to create a directory "Rechtschreibung" with the contents of a "plugin.py" and a "plugin.xml" (code below). I compressed the directory to "Rechtschreibung.zip", but at adding the plugin to Sigil it is refused. OS: Linux Mint 22.3 Cinnamon 64 bit, Sigil v. 2.7.6.

Can someone help, please? Of course, the list is rather short, but I aim to complete it by the time.
