meta property
The _meta property is reserved by ACP to allow clients and agents to attach additional
metadata to their interactions. Implementations MUST NOT make assumptions about values at
these keys. This field is chunk-scoped. Omitted and null are
equivalent and mean no chunk metadata was provided.
See protocol docs: Extensibility
