Is it possible to get the hostname of the host PC connecting to AppStream or Workspaces?

I'm working on a proof of concept with either AppStream or Workspaces and I need to be able to install and run MyPC a PC booking software on AppStream or Workspaces. However, in order for it to work, it needs to know the hostname of the connecting PC that is connecting to AppStream or Workspaces.

In the Registry in the AppStream desktop, I can see where it should be.
