How can we extract startup UWP applications information?

I am using C++ code base to develop a forensic tool. The requirement is to display all the startup applications. However, UWP apps which are enabled to run at startup, are not found in RegEdit at “HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run” or any other paths which have startup applications info.

If I have to write a code to extract Startup applications like Cortana,Skype,Spotify etc (UWP apps) from registry or windows folders, how do I do it? Is there any path where UWP startup applications are stored?

Note: I know that all the installed applications are stored in C:\Program Files\WindowsApps\ but out of them, how to recognize which are startup enabled?
