How does Next Step in Action Buttons differ from Next in Step Completion Rule?

In Action Buttons for Flows, the Next Step is an action that you can add to a custom button in a Flow step. When you add Next Step in Action Buttons in Flows it helps your users to move to the desired next step(s) in the Flow.

For example, you may want your users to move to the next step to “Submit Feedback or “Start Trial” to submit your feedback or begin a process. Use the desired call-to-action text (in this case, use Submit Feedback or Start Trial) when you want to indicate the Next Step in the Flow.

On the other hand, in Step Completion Rule, the rule On click of “next” button is not a custom button, rather a rule that enables end users move to the next step(s) in the Flow.
