Export modal popup panel to pdf?

[cherrypick]

I have a dashboard X consisting of multiple panels (A, B, C) each populated with dynamic tokens. Panel A consists of tabular data. When a user clicks on a cell, this will register table data as tokens. When the token value changes, this will trigger a JavaScript which "activates" panel B which is originally hidden. This will then create a popup consisting of Panel B that is populated with data passed from tokens from panel A. 

Splunk has a default Export to PDF functionality. I know it uses the pdfgen_endpoint.py but how does clicking this button trigger the python script? Currently this functionality works for exporting dashboard X. How do I make adjustments so it can also work for panel B?

/splunkd/__raw/services/pdfgen/render PDF endpoint must be called with one of the following args: 'input-dashboard=<dashboard-id>' or 'input-report=<report-id>' or 'input-dashboard-xml=<dashboard-xml>' but if I try to parse the XML it requires all token values to be resolved. 

Please assist.

Panel B is part of dashboard X, but you say that the export works for dashboard X but not for panel B?

When you say popup, do you mean a modal dialog box on top of the underlying dashboard or just a panel hidden by depends="$token$".

I expect it will not export a modal popup generated through JS.

So the dashboard has 2 visible panels A and C which are shown. Panel B is hidden. So, when I use the default export to pdf it will only show panels A and C which works as intended. Panel B itself is a modal dialog box on top of the underlying dashboard that is also hidden by depends="$token$". 

So ideally I want to adjust the export to pdf functionality to export panel B and not the whole dashboard.
