prefill full conversation from URL params

I’d like to prefill an entire conversation (assistant + user) from a URL parameter (or API or something).

This is an enterprise-y use case. We have a lot of async workflows which are 1-2 back and forths with an assistant (think deep research or single-agent workflows). These usually aren’t triggered by users, but should be followed up with later (e.g. new meeting scheduled, meeting just finished, etc.)

It’d be great to let our users ‘follow-up’ with the workflow’s output by setting up a chatbot UI for them to do so. Would pay a higher tier for this. Don’t want to maintain our own chat UIs just for something like this.
