New required fields detected

Warning

Your PR adds new required fields to an existing destination. Adding new required settings/mappings for a destination already in production requires updating existing customer destination configuration. Ignore this warning if this PR is for a new destination with no active customers in production.

The following required fields were added in this PR:

• Destination: Iterable Lists (Actions), Settings:apiKey
• Destination: Iterable Lists (Actions), Action:syncAudience, Fields:traitsOrProperties,segmentAudienceKey,segmentAudienceId

Add these new fields as optional instead and assume default values in perform or performBatch block.
