Read PDF File Path

Hi,
How do I determine the file path of the PDF file?
I looked in:

but I do not see any relevant information on this.
I also searched the variables, but I don’t see a path:

Do not really understand what the data after “I also searched the variables, but I don’t see a path:” is about, but the documentation page you linked actually answers exactly your question.
It has even an example workflow that does exactly that, and also mentions it specifically:
