Opening PDFs in an external PDF viewer other than the default viewer (ENDNOT X8.2 for MAC)

I am using EndNote X8.2 on a Mac Book Pro 2017 and recently, I contacted the ENDNOTE support to see if there is any way to open up my PDFs in an external PDF application other than the default PDF view?

This is the answer provided by ENDNOTE Product Support Analyst: (I really appreciate their quick answer)

“I am sorry that there is not an option to single click to open the PDF in the external PDF Viewer within EndNote. However, you can also right-click on the PDF in Preview pane in EndNote and click on “Open with Foxit Reader” or “Open with Adobe Reader” or whatever the default program is installed on your computer. This should open the PDF in the external PDF Reader in the program”.
