PS-Skript "Mit Powershell ausführen" - Funktion mit verpflichtende Parameter

Hallo Zusammen,

ich möchte mittels einem PS Skript, Beispielhaft hier, einen AD Benutzer auswählen und entsprechende Informationen exportieren/öffnen.
Hierzu habe eine PS-Skript mit Funktion erstellt, mit verpflichtenden Parameter, was auch soweit funktioniert (ISE F5/F8) oder als PS-Verknüpfung.

Verständnis Frage:
Ich möchte das Script nun “Mit Powershell ausführen” und dabei soll, wenn nicht erfolgt, die benötigen Eingabewerte abgefragt werden.
Führe ich das Script aus, so schließt es sich direkt wieder…

Geht dies überhaupt (so wie mit der F5 ausführen Funktion der ISE) oder muss hier mit ReadHost (vermutlich in der PARAM Sektion) gearbeitet werden?

CODE:
