How do you edit an existing footnote via the graphical editor?

Hi:

Please consider me a newbie, as I have next to no technical skills when it comes to wikis. I edit text and that’s mostly it.

How do you edit an existing footnote that was created using ProseMirror?

For example, at the bottom of this page are some footnotes: https://wiki.freshtomato.org/doku.php/feature_matrix

If I clicked “Edit” in Dokuwiki for the table section with the initial footnotes, I get a field in which it appears I can edit the text, but there is no option to save.

Thanks

ProseMirror is a very generic library with few UI features built into the core. As such, I have no idea how that wiki’s implementation handles footnotes, and this forum isn’t really a good place for end-user questions.

OK. Then where should I ask the question?
