"Save Snapshot" does not open a download window

[gerion0]

ArgoScholar looks extremely promising to manage paper citations. However, for this, I would like to keep the citation graph as part of the overall paper repository, so I need to export it.
Currently, when pressing "Save Snapshot" a hint comes with "If your browser doesn't start downloading the file, you can manually copy the content below and save to a plain text file.". While the copying works, it requires more work than a plain download would cost. The hint suggests, that at least some browsers open a download dialog but I did not find any (I tried Firefox, Chromium, Qutebrowser).
Does this open a download dialog somewhere?

Also, do you know of some possibility to make the whole opening/edit/saving process more comfortable? Ideally, I would like to have the citation file laying together with the remaining files directly in the paper repository for which I need the citations. Ideally, I would open the file, edit the file visually and "just safe it" (or even have an autosave feature). Even with the possibility to download the file directly, the browser directly is not really helpful in opening and saving local files.
When saving the graph as a persistent link on the server. Is there a possibility to get the raw string easily with a script?
