PrintScreeen tied to Snip and Sketch

Followed https://com-puterworks.com/remove_apps.html by launching PowerShell as admin and entering
Get-AppxPackage *Microsoft.ScreenSketch* | Remove-AppxPackage

but PrintScreen still starts Snip and sketch.

A reboot of the OS showed PrintScreen still invokes it.

How do I release PrintScreen so I can use it with Greenshot ?
