Currently the Assistant Beta released on 2024-08-22 is missing the upload feature to submit a website or file (or if the feature is there the UI makes it unclear how to access).
This is a critical feature for a huge portion of my workflow, which often includes submitting a website for the assistant to summarize and have the content available for me to ask further questions or enrich with additional information.
The Assistant Beta should have equivalent UX to the current iteration of the Assistant in which you can provide a website or file (PDF/image).
