CGtarian's Ray rig import into ue4 from maya 2019?

I am completely new beginner to UE4, I want to import the CGtarian’s Ray character rig into UE4 from maya 2019, but
i am having some problems during the importing. I don’t what things to select in ray’s rig before exporting to UE4, and what setting do i need to set on both maya and UE4 in order to successful import of fbx assets. I have been struck with this problem since last 2-3 days.I am sharing some screenshots of problems i have been facing, please look at them below.

Hi, I’m having the exact same problem, have you managed to solve it somehow?
