Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

Current doc "Abort on a function call" is confusing.

In general, I think use abort is not a good thing, we actually need end/finish method.

To Reproduce

The example code actually not work if use { tool_choice: "required" }? It seems await runner.finalFunctionCall() would just throw Error, and all async methods (eg. finalXXX and totalUsage) will throw error anyway after aborted.
