How to use Rdp alternative shell/inital program in Windows 10(education)

Question

I am trying to launch an application using the "alternate shell" option of RDP to start a remote program. But it is not working and I am getting the whole session. Is that feature removed from the window 10? Or am I missing some properties? I simply edited the RDP file to change the alternative shell and executed the file.
