How can I change the message that the customer sees when he e.g. "stop" edited to change? Are you sure you want to cancel? Yes No

Share more details, not clear what you mean

Not sure I understand your request but if it is what I think, then you just gotta change the text field from the question

I mean this message after the customer e.g. Entered Stop.

You just need to modify the question

I searched everything for 2 hours and found nothing. This question is not in my workflow this is global.
