Webapp- Show points within a selected polygon

[RickeyFight]

I have over 3 million points. I cannot have my server displaying all these points on a map a the same time.

What I want to do is when a building is selected, show all points within that polygon.

I know about this example:

Select with Feature Layer | ArcGIS API for JavaScript

I am not sure that will work because I don't want a buffer I want to use another Layer.

Thank you

Thanks for the updated version.  It's exactly what I'm looking for except that I'd like to have the grid table for the point attribute data.  Best if it's edible table.  If you know there's a webapp builder widget for it please let me know. 

Much appreciated
