HDD compatibilty for My Cloud EX2 Ultra

Hello Everyone,
I need your help and your knowledge.
I wanted to know if the HDD Red Plus 4Tb (WD40EFPX) is compatible for the My CLoud EX2 Ultra ?
Why this question because when I see this list, I don’t see the Red Plus 4Tb : https://support-en.wd.com/app/answers/detailweb/a_id/32083/kw/my%20cloud%20ex2%20ultra%20compatibility#subject6
Thank you forward for your feedback and your help.
