6. properties

In a config modifier schema, use properties to define individual properties to construct an object in the processed payload.

This keyword executes at the following nesting level:

1. omit
2. constant
3. references
4. use
5. get
6. properties or if or concat or switch or pipe or merge
7. default
8. plugin

You could define which fields to use to build an object.
