In april 2018 ( maybe earlier) it seems they property definition is returned as part of the Json.
I Implemented some code on the App/full to do something similar, i am not sure i can share the code yet.
The way the rest connecter spits back data you may have to meddle with the Select statement as well as use the peek function.
The rows are sparse / not joined so you will have to use peek to fill in the null values and filter out rows that are null in places.
you will understand when you see it.
I would also suggest filtering down to one individual first till you get the select statement for the REST connection right
add to the connection a query token or use the 'With Connection' Key word'
here is what i used to filter to myself: query=Name eq 'Mackay, Thomas'
