Say you have a flow with a couple of steps, and you want to insert a step in-between.
There are 2 straight-forward ways to do this with the Flow Builder:
The quick way
Click the first step’s button. This also works with triggers and tooltips.
Click its existing Go-to-step action.
Select Add new step.
A new step appears immediately after the first step, and the first step’s button now links to it.
Add a button to the new step.
Link the new button up with the third step.
The drag-and-drop way
Click the Add step button on the far right. You may have to scroll horizontally to reveal it.
Drag the new step in-between the 2 steps where you want it.
Click the first step’s link port and click the new step to change the link.
Add a button to the new step.
Link the new button up with the third step.
