How can I accurately locate a web element in a web page with selector

I need help locating the Xpath or CSS Selector of the download JSON button on this page.

I copied the selector via Chrome browser but it is not locating the button when I control find.

Xpath -> //*[@id=”exportResultsButton”]
CSS -> #exportResultsButton
