Am I missing something here, or should the Run Flow dialog box allow me to select a flow using the thunder bolt?
Can verify this is a bug. Have changed the topic category.
Actually here you need to enter the name of the other flow action you need to run.
So there is no dynamic data involved - so no thunderbolt icon.
Could there be a thunderbolt icon which then shows the other flows available so you can select the flow from the list?
And what if the flow has parameters? 
Show those fields in the same way GET vars are shown when you use an SC API?
Bump. Just noticed this again.
Don't remember seeing your reply 4 years ago. 
The requirement is to have a picker or list to select from existing flows.
Or maybe it should be removed to avoid confusion since we can run flows from the Run step as well.
@George Bump. Thoughts on this?
I think I’m right in saying that if you use the Run step, the flow may execute concurrently, while the Run Flow step ensures it runs sequentially…
Is this correct @George ?
