Would like to understand more how forwardedProps should be used

[pedelman]

Hello, I have recently been exploring ag-ui and I noticed forwardedProps in the docs.

https://docs.ag-ui.com/sdk/js/core/types#runagentinput

type RunAgentInput = {
  threadId: string
  runId: string
  parentRunId?: string
  state: any
  messages: Message[]
  tools: Tool[]
  context: Context[]
  forwardedProps: any
}

I didn't find much information on how this is intended to be used. Is this just an open field to pass anything we want to the agent for custom implementation?
