--toc-title no effect in docx

[huggymann]

Explain the problem.
Using the toc-title it does not have any effect. The title remains "Table of Contents"
pandoc -f html html.html -o outdocx.docx --toc -V --toc-title="Inhaltsverzeichnis" -V mainlang=de --reference-doc=my-ref-doc.docx

Screenshot shows the toc title:

It is expected to change the toc-title. I tried also without the reference-doc , no changes.

Pandoc version?
pandoc 3.1.13 (Ubuntu)
Features: +server +lua
Scripting engine: Lua 5.4

pandoc.exe 3.1.13 (Windows)
Features: +server +lua
Scripting engine: Lua 5.4

i tested both in ubuntu and windows 10

Syntax to set a variable would be

-V toc-title="Inhaltsverzeichnis"

You have an extra --.

Thanks for the clarification. I changed it accordingly, but still no effect. I have a workaround now with metadata "toc-title" that works.
pandoc -f html html.html -o output.docx --toc -V toc-title="Inhaltsverzeichnis" -V mainlang=de

Yes, apparently in docx -M toc-title= works, but not -V toc-title=.
I'll document this.
