Hmm strange, or you deleted your own post, including mine 
answer.
Ok, however. How to solve your ISSUE?
-
First → get userID (you will need this to get specified userData out of PMD)
PMD = PrivateMembersData/PublicMembersData. Here you will need something like this…

If you want to get full user-data, then you will have to make the request on BACKEND…

But, like already mentioned → before you can do this request, you first will have to find out current userID, to provide this information to the request, to be able to get the related user-data.
