Shortcuts - Switch on and immediately off - Homekit Switch

Dear All.

Having real issues with this simple command. I have a switch in Home. I need to speak a Command to Siri and for the switch to be turned on and immediately off again.

I have also created a Scene for that switch, but when loading a new Shortcut there are no controls:

If <input> <condition>

Otherwise -empty-

End If -empty-

I have tried this with or without the Scene, I have followed various instructions, but I have not found any that describe the process in the "If" parts appropriately.

I can currently say "Siri, switch XXXX on", "Siri, switch XXXX off" and it works.

Any help would be much appreciated.
