Add pagenumber to azure search index fields - Integrated Vectorization

[punitsinghi]

Is there a way that I can add original page number which chunk belongs to it. This will help when we show the citation and navigate user to direct page of the pdf rather than showing the full original document. I tried looking at code given as part of DotNetIntegratedVectorizationDemo and modify a bit to see if i can get the page number but couldnt find much.
