If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which topic would you continue discussing?
What contact route would feel appropriate?
What format would help?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: attendees want topic discussions rather than a general chat.
2. Preferred contact routes distinguish interest in further discussion from permission to join a particular channel. Offer actual optional choices and explain participation conditions, without treating survey interest as automatic enrollment consent.
3. Turn the requested improvement into a testable next step. One illustrative action is: offer optional topic-specific groups.
