Is there a way that I can have an interrupt in my Workflow that prompts the user on if they want to proceed forward with an action they just selected or allows them to cancel and stops the workflow?
Yea you can use a pass through condition.
This is for a different scenario, but will show you how to do it:
You can also split the workflow in two:
1 - user selects an action → show popup asking for confirmation
2 - user confirm the popup → your logic
Thanks! Will give these a shot.
