Unable to scrape popup

How to?
#1

Describe the problem.

I am a noob and I am trying to scrape the content of a pop up window which contains citation text information for academic paper. Is it an iframe?

Thanks

Url: https://dl.acm.org/citation.cfm?id=3344518

Sitemap:
{"_id":"bibtex-test","startUrl":["https://dl.acm.org/citation.cfm?id=3344518"],"selectors":[{"id":"link-bibtex","type":"SelectorPopupLink","parentSelectors":["_root"],"selector":"li:nth-of-type(4) li:nth-of-type(1) a","multiple":false,"delay":0},{"id":"text-keyword","type":"SelectorText","parentSelectors":["link-bibtex"],"selector":"div#theformats-body","multiple":false,"regex":"","delay":0}]}

It does not appear to be an iframe. Try this sitemap which works on my PC:

{"_id":"acm-popup-test","startUrl":["https://dl.acm.org/citation.cfm?id=3344518"],"selectors":[{"id":"Title","type":"SelectorText","parentSelectors":["_root"],"selector":"#divmain > div > h1","multiple":false,"regex":"","delay":0},{"id":"Click BibTex","type":"SelectorElementClick","parentSelectors":["_root"],"selector":"ul[title]","multiple":false,"delay":"3000","clickElementSelector":"li a[href*=\"expformat=bibtex\"]","clickType":"clickOnce","discardInitialElements":"do-not-discard","clickElementUniquenessType":"uniqueText"},{"id":"Popup text","type":"SelectorText","parentSelectors":["Popup selector"],"selector":"pre","multiple":false,"regex":"","delay":0},{"id":"Popup selector","type":"SelectorElement","parentSelectors":["_root"],"selector":"div#theformats-body","multiple":false,"delay":0},{"id":"Download URL","type":"SelectorElementAttribute","parentSelectors":["Popup selector"],"selector":"div:nth-of-type(2) a","multiple":false,"extractAttribute":"href","delay":0}]}
