A flat object where each key is a field name and each value can be one of the following types:

• string: Text values
• number: Numeric values
• boolean: true/false values
• date: Unix timestamp (milliseconds since epoch)
• stringList: Multiple string values
• entity: Array of objects representing ownership relations
• file: Filename as a string (file content uploaded separately via presigned URL)

NOTE: The UI in this documentation may only show "string" as the value type, but all types listed above are accepted. Check the examples.

The fields from the conditional type should be included in the root of the object.
