Need ability to show or hide visualization based on button click (API Availability)

I started such a script (below) that doesn't hide but removes confidential visuals. I got caught up in re-adding visuals part. I suspect it could be done through bookmarks or undo functions. Also, in this example, since charts are removed, it resizes all the other visuals which makes for an ugly export :(

# Import namespaces
from Spotfire.Dxp.Framework.ApplicationModel import ApplicationThread
from Spotfire.Dxp.Application.Export import PdfExportSettings
from Spotfire.Dxp.Application.Export import ExportScope
from Spotfire.Dxp.Application.Export import PageOrientation
from Spotfire.Dxp.Application.Export import PaperSize
from Spotfire.Dxp.Application.Export import ExportScope
from Spotfire.Dxp.Application.Visuals import VisualContent, AxisRange


#---------------------------------------------------------------------
# REMOVE SPECIFIC VISUALIZATION(S)
#---------------------------------------------------------------------
for vis in Application.Document.ActivePageReference.Visuals:
	if  "CONFIDENTIAL" in vis.Title:
		Application.Document.ActivePageReference.Visuals.Remove(vis)

#---------------------------------------------------------------------
# EXPORT TO PDF
#---------------------------------------------------------------------

# Declaring the function which will run async
def g(app,fileName,pdfexpsettings):
   def f():      
	  app.Document.Export(pdfexpsettings,fileName)
   return f

# Set the file name
fileName = "C:\\datafiles\\testfile.pdf"
pdfexpsettings = PdfExportSettings()
pdfexpsettings.Scope = ExportScope.ActivePage
pdfexpsettings.PageOrientation = PageOrientation.Landscape
pdfexpsettings.IncludePageTitles = False
pdfexpsettings.IncludeVisualizationTitles = False
pdfexpsettings.IncludeVisualizationDescriptions = False
pdfexpsettings.PaperSize = PaperSize.A4
pdfexpsettings.PageOrientation = PageOrientation.Landscape

# Executing the function on the application thread, and Save the document back to the Library
Application.GetService[ApplicationThread]().InvokeAsynchronously(g(Application, fileName,pdfexpsettings))

# Note:
# The function g is necessary because the script's scope is cleared after execution,
# and therefore Application (or anything else defined in this scope) will not be available
# when the code invokes on the application thread.

This would be useful when printing a page with "confidential" information. A print script could be written that hides confidential charts, prints, then un-hides those charts

I need this as well.
