How do I use 'Do Until' with 'delete items'?

[AOW1]

Hello

I am trying to repeat a 'delete items' action until the number of items in my List is null.

I have tried the below but once the flow runs it says "There are no actions in this Do Until scope" 

thanks

In your screenshot, there is no action inside the "Do Until" Action

Hmm ok how about this?

To be honest I am guessing here as i don't understand how to structure it...
