Improve chat function documentation

I suggest you to update the chat function’s documentation. It is not very obvious that you have to call context.getUserAPI().getUserExists(....) in order to have the function return a value to the SDK. If you don’t call it, then the function just stalls, and the log doesn’t say anything useful to make you aware that it is stalling.

Actually, I think this might be a bug. I thought it was caused by the limit on my free tier plan, but even after I paid, the function invocation doesn’t return a value in my SDK.

Hey @TianrenWang, thanks for the feedback.

Can you DM me the context you’re calling context.getUserApi().getUserExists(...)

I would like to resolve this issue as quickly as possible!
