hey hey everyone, quick question>: Anyone know how to send meta data back from a tool call... This is the payload example from VAPI docs I have but where would i add metadata? { "results": [ { "toolCallId": "call_VaJOd8ZeZgWCEHDYomyCPfwN", "result": "San Francisco's weather today is 62°C, partly cloudy." } ] }. thanks
