Unreal Engine 4 is available for Win10 UWP app dev now

Thank you for your help.
Now I have work package for PC.
But I cannot install this package on my Lumia 950 phone. Because I have next error:

As I understand architecture must be ARM but I have only x86-32 and x64 bit. (I checked their and I have same error in x86 and x64).
Would you like add windows phone as supported device? Or if windows phone already supported what I must do to launch app in my Lumia 950?
