I hope to enable/disable the uwp app's startup items through powershell, but I tried to use gcim win32_startupcommand and Get-Item HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\Run and they couldn’t be found, shell:startup is also empty, it seems that uwp app is invisible and can only be seen in Task Manager->Startup, so what should I do?
