How to open a Windows store app from command line?
start shell:AppsFolder\Microsoft.WindowsTerminal_8wekyb3d8bbwe!App
By default an alias is enabled for Windows Terminal, so you can also use:
"%userprofile%\AppData\Local\Microsoft\WindowsApps\wt.exe"
Example app not from Microsoft:
start shell:AppsFolder\XINGAG.XING_xpfg3f7e9an52!App
Where the string XINGAG.XING_xpfg3f7e9an52
can be found as folder in %userprofile%\AppData\Local\Packages
