You can configure your bot to re-elicit a slot that has already been filled by
setting that slot value to null and setting the next step in the
conversation to loop back to eliciting that slot. For example, you may want to re-elicit a slot after your customer declines a
confirmation of the slot elicitation based on extra information, as in the following
conversation:
You can configure a loop from the confirmation response back to re-elicit the slot with either the intent editor or the Using Visual conversation builder.
Note
You can loop back to re-elicit a slot at any point in the conversation
provided that you set that slot value to null beforehand.

In the Confirmation section of the intent editor, select the right arrow next to Prompts to confirm the intent to expand the section.
-

-
In the Decline response section, select the right arrow next to Set values to expand the section. Fill in this section with the following steps, as in the image below:
